This fixes the bytestream parsing of mpeg-1 stream, but still leaves
open a number of issues with the interpretation:
- IDCT mismatch control is not correct for MPEG-1.
- Slices do not have to start and end on the same horizontal row of macroblocks.
- picture_coding_type = 4 (D-pictures) is not handled.
- full_pel_*_vector is not handled.

The results of a bary.f do not appear to be immediatley available, but
there is no explicit sync bit. Instead the compiler must just ensure
that there are a minimum number of instructions following the bary
before use of the result of the bary. We aren't clever enough for that
so just throw in some nop's.

If we are accumulating result into tmp.x, and need a mov to final
destination, we want to move the .x component into all of the components
enabled from the read dest's writemask, ie. we want:
MOV dst.xyzw tmp.xxxx
rather than:
MOV dst.xyzw tmp.xyzw

This code had no relation to ir_to_mesa.cpp, since it was also used by
intel and state_tracker, and most of it was duplicated with the standalone
compiler (which has periodically drifted from the Mesa copy).
v2: Split from the ir_to_mesa to shaderapi.c changes.

There was nothing ir_to_mesa-specific about this code, but it's not
exactly part of the compiler's core turning-source-into-IR job either.
v2: Split from the ir_to_mesa to glsl/ commit, avoid renaming the sh
variable.

I noticed this while trying to merge code with the builtin compiler, which
does set it.
Note that this causes two regressions in piglit in
default-precision-sampler.* which try to link without a vertex or fragment
shader, due to being run under the desktop glslparsertest binary (using
ARB_ES3_compatibility) that doesn't know about this requirement.

We were duplicating this code all over the place, and they all would need

We have ir->print() to do the old declaration of a visitor and having the
IR accept the visitor (yuck!). And now you can call _mesa_print_ir()
safely anywhere that you know what an ir_instruction is.
A couple of missing printf("\n")s are added in error paths -- when an
expression is handed to the visitor, it doesn't print '\n' (since it might
be a step in printing a whole expression tree).

No more forgetting to #include "ir_print_visitor.h" when doing temporary
debug code, or forgetting and leaving it in after removing your temporary
debug code. Also, available from C code so you don't need to move the
caller to C++ just to call it (see also: ir_to_mesa.cpp).

Not used yet but there's a couple of places in llvmpipe which should use this
(occlusion count is currently very inefficent if there's no cpu popcnt
instruction).
Handle PIPE_QUERY_GPU_FINISHED and PIPE_QUERY_TIMESTAMP_DISJOINT, and
also fill out the ps_invocations and c_primitives from the
PIPE_QUERY_PIPELINE_STATISTICS (the others in there should already
be handled). Note that ps_invocations isn't pixel exact, just 16 pixel
exact but I guess it's better than nothing.
Doesn't really seem to work correctly but there's probably bugs elsewhere.

The driver can do render_condition but wasn't handling the occlusion
and so_overflow predicates (though the latter might not work yet due
to gs support).

The semantics didn't really make sense, not really matching neither d3d9
(though the docs are all broken there) nor d3d10. So make it match d3d10
semantics, which actually gives meaning to the "disjoint" part.
Drivers are fixed up in a very primitive way, I have no idea what could
actually cause the counter to become unreliable so just always return
FALSE for the disjoint part.

The new code makes the shader cache manages all shaders and be able to upload
all of them to a caller-provided bo as a whole.
Previously, we uploaded only the bound shaders. When a different set of
shaders is bound, we had to allocate a new kernel bo to upload if the current
one is busy.

We need to set up a handler for the global_remove event that gets sent
out when a global gets removed. Without the handler we end up calling
a NULL pointer.

When rendering to a texture with BaseLevel set, the miptree may be laid
out such that BaseLevel is in level 0 of the miptree (to avoid wasting
memory on unused levels between 0 and BaseLevel-1). In that case, we
have to shift our render target's level down to the appropriate level of
the smaller miptree.
The WebGL test in combination with a meta code relating to
glGenerateMipmap also triggered a similar failure scenario.
This GPU hang regression was introduced by c754f7a8.

This reverts commit 41966fdb3b.
While it's a lot cleaner it causes regressions because
the draw interface is always called from the draw functions
of the drivers (because the buffers need to be mapped) which
means that the stream output buffers endup being cleared on
every draw rather than on setting.

Also add minimal support for occlusion predicate, though it can't be active
at the same time as an occlusion query yet.
While here also switchify some large if-else (actually just mutually
exclusive if-if-if...) constructs.

For conditional rendering this makes it possible to skip rendering
if either the predicate is true or false, as supported by d3d10
(in fact previously it was sort of implied skip rendering if predicate
is false for occlusion predicate, and true for so_overflow predicate).
There's no cap bit for this as presumably all drivers could do it trivially
(but this patch does not implement it for the drivers using true
hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL
functionality).
