[Mesa-dev] [PATCH 21/21] i965: Use short names for channel_expressions temporaries

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

Reduces the peak ir_variable memory usage in a trimmed apitrace of dota2
by 39KiB on 64-bit.

Before: IR MEM: variable usage / name / total: 5327760 935234 6262994
After:  IR MEM: variable usage / name / total: 5327760 894914 6222674

Reduces the peak ir_variable memory usage in a trimmed apitrace of dota2
by 26KiB on 32-bit.

Before: IR MEM: variable usage / name / total: 4118280 670980 4789260
After:  IR MEM: variable usage / name / total: 4118280 644100 4762380
