We don't actually use it to create all the instructions but we do use it
for insertion always. This should make things far more consistent for
implementing extended instructions.
We do control-flow handling as a two-step process. The first step is to
walk the instructions list and record various information about blocks and
functions. This is where the acutal nir_function_overload objects get
created. We also record the start/stop instruction for each block. Then
a second pass walks over each of the functions and over the blocks in each
function in a way that's NIR-friendly and actually parses the instructions.
Previously, they were hidden behind a #ifdef __cplusplus so C wouldn't find
them. This commit simpliy moves the #ifdef and adds #ifdef's around
constructors.
Instead of having functions to add values and set various things, we just
have a function that does a few asserts and then returns the value. The
caller is then responsible for setting the various fields.
This function's cases for non-generic compressed formats duplicate
the GL to MESA translation in _mesa_glenum_to_compressed_format().
This patch replaces the switch cases with a call to the translation
function. This change teaches this function about ASTC, thus enabling
ASTC for glTex*Storage*() calls.

MESA_FORMAT_RGBA_DXT5 should actually be reserved for GL_RGBA[4]_DXT5_S3TC.
Also, Gallium and other dri drivers (radeon and nouveau) follow this mapping
scheme.

As Glenn did for finalize_loop we need to update_cf when we
add a POP at the end of a shader.
I think this fixes one of the earlier shader going off end
of memory problems we've stopped.

The docs specifically call out SEL with .l and .ge as the
implementations of MIN and MAX respectively. Among other things,
SEL with these conditional mods are commutative.

Certain compressed formats require this setting. The docs don't go into much
detail as to why it's needed exactly.
This patch introduces no piglit regressions on gen9 (bsw is untested). Note that
the SKL "regressions" are fixed tests, and the egl_khr_gl_colorspace tests are
WTF. The patch also fixes nothing I can find.

v2:
Reworded commit message (Matt); Added piglit results link.
Restructured condition (Matt)
Moved check out to function (Nanley). I left the setting of the bit in the
surface state open coded because it seems to go better with the existing code.
v3:
Use and inline function only in gen8_emit_texture_surface_state() (Matt).

This can be done with a single pass for the instruction base,
and takes renumber_registers out of its spot on the profile.

The glsl->tgsi convertor does some temporary register reduction
however in profiling shader-db this shows up quite highly,
so optimise things to reduce the number of loops through
all the instructions we do. This drops merge_registers
from 4-5% on the profile to 1%. I think this can be reduced
further by possibly optimising the renumber pass.

Instead of looking this up lots, lets just cache it in the instruction
translation up front. I just noticed this function what high in a profile
of shader-db on radeonsi.

The selector is shared by all shader variants, so the
individual shaders shouldn't change it. Use tgsi_shader_scan()
results to set geometry properties within a
r600_create_shader_state() call and treat said propertices in
the selector as read-only within r600_shader_from_tgsi().
