Compiler intrinsics

Add intrinsic support.  Some of these appear to be of
limited value, so we may end up removing a few.  In general,
the instrinsics provide small, but measurable, gains.

Only Arm is currently supported, but most of these should
work for our other targets as well.

This is an interim solution.  My plan is to the intrinsic
recognition action up into the basic block building phase once
we start doing inlining.
