d674ebcee0 glsl2: Add a pass to simplify if statements returning from both sides. 
This allows function inlining making the following tests work even
without function calls implemented:
glsl-fs-functions-2
glsl-fs-functions-3
glsl-vs-functions
glsl-vs-functions-2
glsl-vs-functions-3
glsl-vs-vec4-indexing-5

(Note that those tests were designed to trigger actual function calls,
and this defeats them.  However, those testcases ended up catching the
bug in the previous commit.)

773025b92c glsl2: Don't forget to walk the parameters to a function in the hv.

free of the compile context.

d4d630b72c glsl2: Put the declaration in the instruction stream before its initializer.

ir_validate.cpp-driven rework of assignments.

a36334be02 glsl2: Add pass for supporting variable vector indexing in rvalues. 
The Mesa IR needs this to support vector indexing correctly, and
hardware backends such as 915 would want this behavior as well.

Fixes glsl-vs-vec4-indexing-2.

ca088cc277 glsl2: Clone methods return the type of the thing being cloned 
This is as opposed to returning the type of the base class of the hierarchy.

37b3f9d0ed ir_constant_expression: Support scalar * vector and scalar * matrix. 
The test here is slightly different since we need to keep matrix
multiplication separate.

Fixes piglit tests const-vec-scalar-03.frag and const-mat-scalar-03.frag.

6bc432e14e ir_constant_expression: Initialize op[0] and op[1] to NULL. 
This makes it easy to check if there is a second argument.

c63a1db81f ir_constant_expression: Initialize all components of constant data to 0. 
This is probably just a good idea, and will come in useful when
implementing things like matrix multiplication.

667f4e1940 glsl2: Conditionally allow optional extensions to be enabled

efb6b24223 glsl2: Append _TOK to some parser tokens 
This prevents conflicts with defines elsewhere in Mesa and allows
including mtypes.h in the compiler.

2d12236117 glsl2: Define preprocessor tokens for extensions 
Currently only GL_ARB_draw_buffers and GL_ARB_texture_rectangle are
defined because those extensions are always enabled.  This make
tex_rect-03.frag pass.

d925c91730 glsl2: Add ir_unop_fract as an expression type. 
Most backends will prefer seeing this to seeing (a - floor(a)), so
represent it explicitly.

4e16a7b526 glsl2: Fix up the implementation of fract() for vector types. 
There's no need to split each vector component out, just do vector ops.

97eba76b8c glsl2: Allow a fragment shader to not write a color. 
I can't find any text justifying this check, and it caused a
reasonable-looking shader in glsl-bug-22603 (which writes only
gl_FragDepth) to fail.

c7f4ff193a glsl2: Fix storing of dead memory in the symbol table. 
decl->identifier is part of the AST, so it doesn't live very long.
Instead, add var->name which is owned by var.

Kenneth Graunke
953ff1283d glsl2: Use _mesa_glsl_parse_state as the talloc parent, not glsl_shader. 
_mesa_glsl_parse_state should be the parent for all temporary allocation
done while compiling a shader.  glsl_shader should only be used as the
parent for the shader's final IR---the _result_ of compilation.

Since many IR instructions may be added or discarded during optimization
passes, IR should not ever be allocated to glsl_shader directly.

Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g.

This also removes a ton of talloc_parent calls, which may help performance.
