i965/fs: Enforce extended math exec size limits during SIMD lowering.

This teaches the SIMD lowering pass about the hardware limits on the
execution size of math instructions, which will allow simplifying the
generator code and at the same time get rid of a number of bugs in the
manual SIMD unrolling done currently that prevent SIMD32 codegen from
working.
