[Mesa-dev] GLSL compile time improvements

[Thomas Helland]

Patch 7 has my RB. I'll look closer at the rest this evening.
There's also the stringbuffer work that I have lying that should help.
I just have to find out how to run the gtest tests to verify their working.

This series reduces compile times of the Deus Ex shaders on my
Ryzen 1800X from 2m27s -> 2m8s with a cold cache on radeonsi.

Note: The above times are from compiling the shaders with shader-db
on a single thread, starting the actual game results in around
double the time/improvement.

The aim of the series was to target overhead in the parser/AST
sections of the compiler. I believe there is probably still more
low hanging fruit in the AST code. I've been profiling this by
compiling the shaders once and then deleting the index file from
the cache.

Please review.
