glsl: Squish ir_variable::max_ifc_array_access and ::state_slots together
At least one of these pointers must be NULL, and we can determine which
will be NULL by looking at other fields. Use this information to store
both pointers in the same location.
If anyone can think of a better name for the union than "u", I'm all
ears.
Valgrind massif results for a trimmed apitrace of dota2:
n time(i) total(B) useful-heap(B) extra-heap(B) stacks(B)
Before (32-bit): 63 40,574,239,515 68,117,280 62,618,607 5,498,673 0
After (32-bit): 44 40,577,049,140 68,118,608 62,441,063 5,677,545 0
Before (64-bit): 53 37,126,451,468 95,150,256 87,711,304 7,438,952 0
After (64-bit): 63 37,122,829,194 95,153,008 87,333,600 7,819,408 0
A real savings of 173KiB on 32-bit and 368KiB on 64-bit.
