glsl: Eliminate ir_variable::data.atomic.buffer_index
Just use ir_variable::data.binding... because that's the where the
binding is stored for everything else that can use layout(binding=).
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): 50 40,564,927,443 69,185,408 63,683,871 5,501,537 0
After (32-bit): 74 40,580,119,657 69,186,544 63,506,327 5,680,217 0
Before (64-bit): 59 36,822,048,449 96,526,888 89,113,000 7,413,888 0
After (64-bit): 89 36,822,971,897 96,526,616 88,735,296 7,791,320 0
A real savings of 173KiB on 32-bit and 368KiB on 64-bit.
