The GS has an interesting use for mul. Because the GS can emit multiple
vertices per input vertex, and it also has a unique count at the top of the URB
payload, the GS unit needs to be able to dynamically specify URB write offsets
(relative to the global offset). The documentation in the function has a very
good explanation from Paul on the mechanics.
This fixes around 2000 piglit tests on BSW.

Three source instructions cannot directly source a packed vec4 (<0,4,1>
regioning) like vec4 uniforms, so we emit a MOV that expands the vec4 to
both halves of a register.
If these uniform values are used by multiple three-source instructions,
we'll emit multiple expansion moves, which we cannot combine in CSE
(because CSE emits moves itself).
So emit a virtual instruction that we can CSE.
Sometimes we demote a uniform to to a pull constant after emitting an
expansion move for it. In that case, recognize in opt_algebraic that if
the .file of the new instruction is GRF then it's just a real move that
we can copy propagate and such.

Nowadays GCC assumes stack pointer is 16-byte aligned even on 32-bits,
but that is an assumption OpenGL drivers (or any dynamic library for
that matter) can't afford to make as there are many closed- and open-
source application binaries out there that only assume 4-byte stack
alignment.
This fix uses force_align_arg_pointer GCC attribute, and is only a
stop-gap measure.
The right fix would be to pass -mstackrealign or
-mincoming-stack-boundary=2 to all source fails that use any -msse*
option, as there is no way to guarantee if/when GCC will decide to spill
SSE registers to the stack.

BRW_NEW_VERTICES is flagged every time we draw a primitive. Having
the brw_vs_prog atom depend on BRW_NEW_VERTICES meant that we had to
compute the VS program key and do a program cache lookup for every
single primitive. This is painfully expensive.
The workaround bit computation is almost entirely based on the vertex
attribute arrays (brw->vb.inputs[i]), which are set by brw_merge_inputs.
The only thing it uses the VS program for is to see which VS inputs are
actually read. brw_merge_inputs() happens once per primitive, and can
safely look at the currently bound vertex program, as it doesn't change
in the middle of a draw.
This patch moves the workaround bit computation to brw_merge_inputs(),
right after assigning brw->vb.inputs[i], and stores the previous WA bit
values in the context. If they've actually changed from the last draw
(which is uncommon), we signal that we need a new vertex program,
causing brw_vs_prog to compute a new key.
Improves performance in Gl32Batch7 by 13.6123% +/- 0.739652% (n=166)

v2: Introduce a new BRW_NEW_VS_ATTRIB_WORKAROUNDS dirty bit, rather
than reusing BRW_NEW_VERTEX_PROGRAM (suggested by Chris Forbes).
This prevents unnecessary re-emission of surface/sampler related

We use IEEE mode for GLSL programs, but need to use ALT mode for ARB
programs so that 0^0 == 1. The choice is based entirely on the shader
source language.
Previously, our code to determine which mode we wanted was duplicated
in 8 different places (VS and FS for Gen4-5, Gen6, Gen7, and Gen8).
The ctx->_Shader->CurrentProgram[stage] == NULL check was confusing
as well - we use CurrentProgram (non-derived state), but _Shader
(derived state). It also relies on knowing that ARB programs don't
use gl_shader_program structures today. The compiler already makes
this assumption in a few places, but I'd rather keep that assumption
out of the state upload code.
With this patch, we select the mode at compile time, and store that
choice in prog_data. The state upload code simply uses that decision.
This eliminates a BRW_NEW_*_PROGRAM dependency in the state upload code.

Nine code to match vertex declaration to vs inputs was limiting
the number of possible combinations.
Some sm3 games have issues with that, because arbitrary (usage/index)
can be used.
This patch does the following changes to fix the problem:
. Change the numbers given to (usage/index) combinations to uint16
. Do not put limits on the indices when it doesn't make sense
. change the conversion rule (usage/index) -> number to fit all combinations
. Instead of having a table usage_map mapping a (usage/index) number to
an input index, usage_map maps input indices to their (usage/index)

With sm3, you can declare an input/output with an usage and an usage index.
Nine code hardcodes the translation usage/index to a corresponding TGSI code.
The translation was limited to a few usage/index combinations that were corresponding
to most of the needs of games, but some games did not work.
This patch rewrites that Nine code to map all possible usage/index combination
to TGSI code. The index associated to TGSI_SEMANTIC_GENERIC doesn't need to be low
for good performance, as the old code was supposing, and is not particularly bounded
(it's UINT16). Given the index is BYTE, we can map all combinations.
