b2d7ed2aba glsl2: Don't clear swizzles for Mesa IR constants after fetching them. 
Missed this while hacking in constants support.  Fixes:
glsl-algebraic-mul-*
glsl-algebraic-rcp-*
glsl-vs-swizzle-swizzle-lhs
glsl-vs-vec4-indexing-6

78062273de ir_reader: Free memory for S-Expressions earlier. 
There's no point in keeping it around once we've read the IR.

Also, remove an unnecessary talloc_parent call.

85c978f38c glsl2: Start trying to hook up uniforms. 
This should be resolved with linker.cpp's location assignment, as
currently we drop that location assignment on the ground.  However,
this gets basic programs using uniforms working for now.

8ebfcf31eb draw: limit the number of vertex shader variants kept around 
we used to create and cache unltimited number of variant, this
change limits the number of variants kept around to a fixed number.
the change is based on a similar patch by Roland for llvmpipe fragment
shaders.

bda27424cf glsl2: Use the parser state as the talloc context for dead code elimination. 
This cuts runtime by around 20% from talloc_parent() lookups.

364fcd8ee1 glsl2: Start integrating ir_to_mesa.cpp into shader_api.h 
The compiler is now called by the driver, and generates program
instructions.  Parameter lists are still not set up, so the driver
chokes on it shortly thereafter.

output array as a workaround.

a879d14ecf mesa: initialize extension string when context is first bound 
...instead of waiting until glGetString(GL_EXTENSIONS) is called.
This fixes a problem where the MESA_EXTENSION_OVERRIDE env var is
ignored if the app never calls glGetString(GL_EXTENSIONS).

NOTE: this is a candidate patch for the 7.8 branch.

bcc13b7444 Merge branch 'glsl2-head' into glsl2 
This brings in the standalone GLSL compiler that we are planning on
replacing the existing Mesa GLSL compiler.  It currently targets GLSL
1.20 and the Mesa IR.

0ee7d80269 Merge branch 'mesa' 
This brings in the ir_to_mesa.cpp code I've been developing to codegen
to the Mesa IR.  It does not actually generate a complete Mesa
fragment/vertex program yet.

6b01b50888 Move the talloc_parent lookup down in a few hot paths. 
talloc_parent is still 80% of our runtime, but likely talloc_parent
lookups will be reduced as we improve the handling of memory
ownership.

e33c10328c Merge remote branch 'cworth/master' 
Conflicts:
	ast_to_hir.cpp
	ir.cpp

This brings in the talloc-based memory management work, so that the
compiler (almost) no longer leaks memory.

8364fc85b8 ir_to_mesa: Handle a limited subset of matrix multiplication. 
glsl-mvp.vert now generates believable code, and mesa mode fails only
5 tests that master doesn't.  I must have left out some asserts...

7672064756 ir_to_mesa: Handle constant matrices. 
There's not much to it since we're not actually storing constant data yet.

554dbcce77 ir_to_mesa: Move the classes into the file now that we don't have the burg. 
At 1kloc, it doesn't look like I'll want to split the ir_to_mesa file
up even once it's feature-complete.  Move definitions closer to usage,
and prevent rebuilding the world when changing the definitions.

0161515c39 ir_to_mesa: Remove the BURG code. 
The promise of the BURG was to recognize multi-instruction sequences
and emit reduced sequences for them.  It would have worked well for
recognizing MUL+ADD -> MAD and possibly even MIN(MAX(val, 0), 1) ->
MOV_SAT with some grammar changes.  However, that potential benefit in
making those optimizations easy is outweighed by the fragility of
monoburg, the amount of (incorrect, as I wrote it) code for using it,
and the burden it was going to cause for handling operations on
aggregate types.
