glsl: Don't allocate a name for ir_var_temporary variables
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 40,578,719,715 67,762,208 62,263,404 5,498,804 0
After (32-bit): 52 40,565,579,466 66,359,800 61,187,818 5,171,982 0
Before (64-bit): 74 37,129,541,061 95,195,160 87,369,671 7,825,489 0
After (64-bit): 76 37,134,691,404 93,271,352 85,900,223 7,371,129 0
A real savings of 1.0MiB on 32-bit and 1.4MiB on 64-bit.
