Add for now some simple/basic query support (ie. things not actually
requiring the GPU). Might change around a bit when I actually add
GPU queries, but for now this enables some useful performance info
in the GALLIUM_HUD. For example:
GALLIUM_HUD=fps+batches+batches-sysmem+batches-gmem+restores,draw-calls
The driver specific specific queries are:
+ draw-calls
+ batches - number of batches per second, sum of batches-sysmem
plus batches-gmem
+ batches-gmem - render a set of tiles in GMEM, for each tile
(optionally) system mem -> gmem (restore), plus N draws,
plus gmem -> system mem (resolve) per second
+ batches-sysmem - N draws to system memory (GMEM bypass) per
second
+ restores - number of GMEM batches that required restore per
second
Ideally for GMEM rendering, you want batches-gmem to equal fps. If
the app is doing something that triggers multiple passes (ie. requires
extra round trip gmem <-> system memory) then the # of batches per
second will go up relative to fps.

The binning pass sorts vertices into which bins/tiles they apply to.
The visibility information generated during the binning pass can be
used to speed up the rendering pass by filtering out vertices which
do not apply to the current tile. See:

This brings a significant fps boost. A rough assortment of tests
(supertuxkart, etracer, tremulous, glmark2 'build' test, etc) seems
to yield a ~35-45% fps improvement.
For now, to be conservative, the binning pass is not enabled yet by

gl_shader_stage to represent pipeline stages; using gl_shader::Stage
in those functions avoids the need for a conversion.

inconsistently named functions for converting between it and other

The preprocessor has always replaced multi-line comments with a single space
character, (as required by the specification), but as of commit
bd55ba568b the lexer also emitted a NEWLINE
token for each newline within the comment, (in order to preserve line
numbers).
The emitting of NEWLINE tokens within the comment broke the rule of "replace a
multi-line comment with a single space" as could be exposed by code like the
following:
#define FOO a/*
*/b
FOO
Prior to commit bd55ba568b, this code defined
the macro FOO as "a b" as desired. Since that commit, this code instead
defines FOO as "a" and leaves a stray "b" in the output.
In this commit, we fix this by not emitting the NEWLINE tokens while lexing
the comment, but instead merely counting them in the commented_newlines
variable. Then, when the lexer next encounters a non-commented newline it
switches to a NEWLINE_CATCHUP state to emit as many NEWLINE tokens as
necessary (so that subsequent parsing stages still generate correct line
numbers).
Of course, it would have been more clear if we could have written a loop to
emit all the newlines, but flex conventions prevent that, (we must use
"return" for each token we emit).
It similarly would have been clear to have a new rule restricted to the
<NEWLINE_CATCHUP> state with an action much like the body of this if
condition. The problem with that is that this rule must not consume any
characters. It might be possible to write a rule that matches a single
lookahead of any character, but then we would also need an additional rule to
ensure for the <EOF> case where there are no additional characters available
for the lookahead to match.
Given those considerations, and given that the SKIP-state manipulation already
involves a code block at the top of the lexer function, before any rules, it
seems best to me to go with the implementation here which adds a similar
pre-rule code block for the NEWLINE_CATCHUP.
Finally, this commit also changes the expected output of a few, existing glcpp
tests. The change here is that the space character resulting from the
multi-line comment is now emitted before the newlines corresponding to that
comment. (Previously, the newlines were emitted first, and the space character
afterward.)

Using RMW on banked context registers is not safe. The value read
could be the wrong one. So if there has been a DRAW_IDX launched,
the RMW must be preceded by a WAIT_FOR_IDLE to ensure the read part
of RMW sees the correct value.
To avoid unnecessary WFI's, keep track if there is a need for WFI,
and only emit one if needed. Furthermore, keep track if we even
need to update the register in the first place.
And to cut down on the amount of RMW to avoid excessive WFI's, at the
tiling/GMEM level we can always overwrite RB_RENDER_CONTROL, as the
state at beginning of draw/clear cmds (which we IB to) is always
undefined. In the draw/clear commands, we always still use RMW (with
WFI if needed), but only if the register value actually changes. (At
points where the current value cannot be known, the saved value is
reset to ~0, which includes bits outside of RBRC_DRAW_STATE, so there
never is chance for confusion.)

Actually assign VSC_PIPE's properly, which will be needed for tiling.
And introduce fd_tile for per-tile state (including the assignment of
tile to VSC_PIPE). This gives us the proper pipe setup that we'll
need for hw binning pass, and also cleans things up a bit by not having
to pass so many parameters around. And will also make it easier to
introduce different tiling patterns (since we may no longer render
tiles in a simple left-to-right top-to-bottom pattern).

Previously we were creating a new LLVMContext every time that we called
radeon_llvm_parse_bitcode, which caused us to leak the context every time
that we compiled a CL program.
Sadly, we can't dispose of the LLVMContext at the point that it was being
created because evergreen_launch_grid (and possibly the SI equivalent) was
assuming that the context used to compile the kernels was still available.
Now, we'll create a new LLVMContext when creating EG/SI compute state, store
it there, and pass it to all of the places that need it.
The LLVM Context gets destroyed when we delete the EG/SI compute state.

While looking through the documentation, I found this in the Sandybridge
PRM (Volume 4, Part 1, Page 140):
"Use of sample_c with SURFTYPE_CUBE surfaces is undefined with the
following surface formats: I24X8_UNORM, L24X8_UNORM, A24X8_UNORM,
I32_FLOAT, L32_FLOAT, A32_FLOAT."
I haven't observed this to be true, but it suggests that we may want to
use other formats.
We already perform DEPTH_TEXTURE_MODE swizzling in the shaders, and
don't rely on the surface format to splat things appropriately. So
using RED should work just as well as INTENSITY.
A few notes about the formats:
- R24_UNORM_X8_TYPELESS has the exact same properties as I24X8_UNORM.
- R16_UNORM and R32_FLOAT are additionally supported as a render target,
while the old I16_UNORM/I32_FLOAT formats are not.
- R32_FLOAT_X8X24_TYPELESS is not supported as a render target, while
the old format (R32G32_FLOAT) was. However, it shares the same
properties as the formats we use for Z24, so it should suffice.
This makes translate_tex_format and brw_blorp_surface_info::set
a bit more similar.

Broadwell allows us to specify an arbitrary value for QPitch, rather
than baking a specific formula into the hardware and requiring software
to lay things out to match. The only restriction is that the software
provided QPitch needs to be large enough so successive array slices do
not overlap.
In order to support this flexibility, software needs to specify QPitch
in a bunch of packets. Storing QPitch makes that easy, and allows us to
adjust it in a single place should we wish to change it in the future.

On released hardware, values 4-6 are overloaded. For normal registers,
they mean UB/B/DF. But for immediates, they mean UV/VF/V.
Previously, we just created #defines for each name, reusing the same
value. This meant we could directly splat the brw_reg::type field into
the assembly encoding, which was fairly nice, and worked well.
Unfortunately, Broadwell makes this infeasible: the HF and DF types are
represented as different numeric values depending on whether the
source register is an immediate or not.
To preserve sanity, I decided to simply convert BRW_REGISTER_TYPE_* to
an abstract enum that has a unique value for each register type, and
write translation functions. One nice benefit is that we can add
assertions about register files and generations.
I've chosen not to convert brw_reg::type to the enum, since converting
it caused a lot of trouble due to C++ enum rules (even though it's
defined in an extern "C" block...).
