glsl: Use a single bit for the dual-source blend index
The only values allowed are 0 and 1, and the value is checked before
assigning.
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): 74 40,580,119,657 69,186,544 63,506,327 5,680,217 0
After (32-bit): 76 40,572,916,873 68,831,248 63,328,783 5,502,465 0
Before (64-bit): 89 36,822,971,897 96,526,616 88,735,296 7,791,320 0
After (64-bit): 60 36,822,640,058 96,526,824 88,735,296 7,791,528 0
A real savings of 173KiB on 32-bit and no change on 64-bit.
