I don't see the point of asking him to do that. It would be a significant amount of
work which would be wasted once Szabolcs posts his implementation.

What I'd like to ask Ashwin is which benchmarks show a speedup due to
his patch and whether it is essential they get a speedup this release
(rather than a larger speedup later). I don't recall seeing sinf/cosf in profiles
in popular benchmarks, so I don't understand the urgency of doing this now.

What I think would be useful is to start collecting real traces of actual applications
or large benchmarks like SPEC and creating representative microbenchmarks
using that data.
