dfd30ca6a9 glsl2: Remove generate_temporary and global temporary counter. 
Most places in the code simply use a static name, which works because
names are never used to look up an ir_variable.  generate_temporary is
simply unnecessary (and looks like it would leak memory, and isn't
thread safe...)

25cda5039d mesa: Extend register lifetimes to the end of the largest loop required. 
Previously, a register defined at main scope and used in a loop in a
loop could end up getting marked as needed only from the definition
outside of the loops to the end of the inner loop, and we would
cleverly slot in something else in its register in the end of the
outer loop.

Fixes glsl-vs-loop-nested and glsl-fs-loop-nested on glsl2.  This
doesn't happen much on master because the original compiler does its
own register allocation, so we find little we can do with linear scan
register (re)allocation.

f632a330ec mesa: Fix documentation of BranchTarget for BRK. 
It was changed in 2009 and the comment wasn't updated.

152b55e74d glsl2: Add support for gl_PointCoord in 1.20. 
Fixes glsl-fs-pointcoord on swrast (remains broken on 965, like master)

ea2a03f0a5 ir_to_mesa: Fix the assertion on LHS array derefs to DWIM. 
This allows array derefs of matrices now, which makes idr's GLSL demo
happy.

b4d0c0e0ee ir_to_mesa: Add support for adding/subtracting matrices. 
This isn't really tested, but didn't break normal vector add/sub.

35c89204e5 linker: Use bit-0 instead of VERT_BIT_GENERIC0 
Uses of the bits for allocation are offset by 16, and
VERT_BIT_GENERIC0 already has the 16 offset.  As a result, it was
preventing the wrong thing from being allocated.

0b74bbb3dc glsl: Fix the setup of refract()'s output for vec3/vec4 and k < 0.0.

9cbd8a1d5a glsl2: Fix ir_div_to_mul_rcp for integer division. 
rcp of an integer value did not produce the result you're looking for.
Instead, do the a * rcp(b) as float and truncate after.  This mostly
fixes glsl-fs-loop-nested.

2e85f993d8 Revert "glsl2: Put the declaration in the instruction stream before its initializer." 
This change causes segfaults in other tests.  A fix for both sets of
segfaults is coming.

This reverts commit d4d630b72c.

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. 
This fixes a regression in the generated code from when I did the
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

multiplication separate.

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.

a0b3b93029 ir_to_mesa: Use the compiler-assigned locations for builtin attrs/varyings. 
The previous table didn't distinguish gl_Color for the VS and FS, so
we would use the FS's attribute index for the VS and read undefined.
This partially fixes glsl-routing to match its behavior on master.
