Marek Olšák 3c4a64e807 nir: eliminate most ralloc/malloc for nir_variable names
Store small names in a fixed-sized string in nir_variable.
GLSL IR does the same thing.

When compiling my shader-db with the gallium noop driver, it improves GLSL
compile times by 0.7% (much lower than anticipated).

For Unigine Heaven shaders:
- it eliminates 95.6% ralloc calls for nir_variable names
- the total number of ralloc calls is reduced by 11%

It also adds only 16B to nir_variable, while just the ralloc header
for the name would occupy 40B.
