REGRESSION (r37991): Occasionally see "Scene rendered incorrectly"
message when running the V8 Raytrace benchmark

Rolled out r37991. It didn't properly save xmm0, which is caller-save,
before calling helper functions.

SunSpider and v8 benchmarks show little change -- possibly a .2%
SunSpider regression, possibly a .2% v8 benchmark speedup.
