This will be used on Gen8+ to make sure that the color calculator
state pointers are re-emitted when switching back to the 3D pipeline
after some GPGPU workload due to a hardware workaround. There are
other state bits already defined that could be used to achieve the
same effect but they all cause a ton of unrelated state to be
re-emitted (e.g. BRW_NEW_STATE_BASE_ADDRESS), so just define a new
one, state bits are cheap.

Reduces local memory usage in a lot of Metro 2033 Redux and a few KSP
shaders:
total local used in shared programs : 54116 -> 30372 (-43.88%)
Probably modest advantage to execution, but it's an imporant
prerequisite to dropping some of the TGSI optimizations done by the

Previously we were treating any indirect temp array usage to mean that
everything should end up in lmem. The MemoryOpt pass would clean a lot
of that up later, but in the meanwhile we would lose a lot of
opportunity for optimization.
This helps a lot of Metro 2033 Redux and a handful of KSP shaders:
total instructions in shared programs : 6288373 -> 6261517 (-0.43%)
total gprs used in shared programs : 944051 -> 945131 (0.11%)
total local used in shared programs : 54116 -> 54116 (0.00%)
A typical case is for register usage to double and for instructions to
halve. A future commit can also optimize local memory usage size to be
reduced with better packing.

Indirect constbuf indexing works by using very large offsets. However if
an indirect constbuf index load is const-propagated, it becomes a very
large const offset. Take that into account when legalizing the SSA by
moving the high parts of that offset into the file index. Also disallow
very large (or small) indices on most other instructions.
This fixes regressions in ubo_array_indexing/*-two-arrays piglit tests.

The OpenGL specifications for bitfieldExtract() says:
The result will be undefined if <offset> or <bits> is negative, or if
the sum of <offset> and <bits> is greater than the number of bits
used to store the operand.
Therefore passing bits=32, offset=0 is legal and defined in GLSL.
But the earlier SM5 ubfe/ibfe opcodes are specified to accept a bitfield width
ranging from 0-31. As such, Intel and AMD instructions read only the low 5 bits
of the width operand, making them not able to implement the GLSL-specified
behavior directly.
This commit adds ubfe/ibfe operations from SM5 and a lowering pass for
bitfield_extract to to handle the trivial case of <bits> = 32 as

The internal Mesa format used for a texture might not match the one
requested in the internalFormat when the texture was created, for
example if the driver is internally remapping RGB textures to RGBA.
Otherwise it can cause false positives for completeness if one mipmap
image is created as RGBA and the other as RGB because they would both
have an RGBA Mesa format. If we check the InternalFormat instead then
we are directly checking the API usage which I think better matches
the intention of the check.

The RGBX surface formats aren't renderable so we internally remap them
to RGBA when rendering. They are retained as RGBX when used as
textures. However since the previous patch fast clears are disabled
for surfaces that use a different format for rendering than for
texturing. To avoid this situation we can just pretend not to support
RGBX formats at all. This will cause the upper layers of mesa to pick
an RGBA format internally instead. This should be safe because we
always override the alpha component to 1.0 for RGBX in the texture
swizzle anyway. We could also do this for all gens except that it's a
bit more difficult when the hardware doesn't support texture
swizzling. Gens using the blorp have further problems because that
doesn't implement this swizzle override.
