I had this note to myself, and it turns out that a lot of CTS tests use
XFB with points to get data out without using a fragment shader. Keep
track of two sets of precomputed TF specs (point size in VPM prologue or
not), and switch between them when we enable/disable point size.
The length-1 field only has 4 bits, so we need to generate separate specs
when there's too much TF output per buffer.
Fixes
GTF-GLES3.gtf.GL3Tests.transform_feedback.transform_feedback_builtin_type
and transform_feedback_max_interleaved.
GTF-GLES3.gtf.GL3Tests.instanced_arrays.instanced_arrays_divisor uses -1
as a divisor, so we would overflow to count=0 and upload no data,
triggering the assert below. We want to upload 1 element in this case,
fixing the test on VC5.
v2: Use some more obvious logic, and explain why we don't use the normal
round_up().

There's nothing to worry about here -- the A channel just gets dropped by
the blit. This avoids a segfault in the fallback path when copying from a
RGBA16_SINT renderbuffer to a RGB16_SINT destination represented by an
RGBA16_SINT texture (the fallback path tries to get/fetch to float
buffers, but the float pack/unpack functions are NULL for SINT/UINT).
Fixes KHR-GLES3.packed_pixels.pbo_rectangle.rgba16i on VC5.
v2: Extract the logic to a helper function and explain what's going on
better.

Just checking for 2 jumps is not enough to be sure we can do a
complex loop unroll. We need to make sure we also have also found
2 loop terminators.
Without this we were attempting to unroll a loop where the second
jump was nested inside multiple ifs which loop analysis is unable
to detect as a terminator. We ended up splicing out the first
terminator but failed to actually unroll the loop, this resulted
in the creation of a possible infinite loop.

A recent commit (see below) triggered some cases where conditional
modifier propagation and dead code elimination would cause a MAD
instruction like the following to be generated:
mad.l.f0 null, ...
Matt pointed out that fs_visitor::fixup_3src_null_dest() fixes cases
like this in the scalar backend. This commit basically ports that code
to the vec4 backend.
NOTE: I have sent a couple tests to the piglit list that reproduce this
bug *without* the commit mentioned below. This commit fixes those
tests.

This method is similar to the existing ::equals methods. Instead of
testing that two src_regs are equal to each other, it tests that one is
the negation of the other.
v2: Simplify various checks based on suggestions from Matt. Use
src_reg::type instead of fixed_hw_reg.type in a check. Also suggested
by Matt.
v3: Rebase on 3 years. Fix some problems with negative_equals with VF
constants. Add fs_reg::negative_equals.
v4: Replace the existing default case with BRW_REGISTER_TYPE_UB,
BRW_REGISTER_TYPE_B, and BRW_REGISTER_TYPE_NF. Suggested by Matt.

The currently we use the singular CHECK_HEADER combined with explicit
append to the DEFINES variable. That is a legacy misnomer, since it
requires us to add $DEFINES to every piece that we build.
Using the plural version of the helper sets the HAVE_ macro for us, plus
ensures it's passed to the compiler - if config.h is available in there
(not in the case of mesa) otherwise on the command line.
In hindsight, we should replace all the AC_CHECK_{FUNC,HEADER} instances
with the plural version (or even the _ONCE suffixed version) and drop
the DEFINES hacks.

The hardware only supports 32-bit depth surfaces, but we can
enable TC-compat HTILE for 16-bit depth surfaces if no Z planes
are compressed.
The main benefit is to reduce the number of depth decompression
passes. Also, we don't need to implement DB->CB copies which is
fine.
This improves Serious Sam 2017 by +4%. Talos and F12017 are also
affected but I don't see a performance difference.
This also improves the shadowmapping Vulkan demo by 10-15%
(FPS is now similar to AMDVLK).
