If 2.5 ulp is acceptable, denormals are not required, and
isn't a reciprocal which will already be handled, replace
with a faster fdiv.
Simplify the lowering tests by using per function
subtarget features.

Summary:
IntrReadWriteArgMem simply becomes IntrArgMemOnly.
So there are fewer intrinsic properties that express their orthogonality
better, and correspond more closely to the corresponding IR attributes.

I did my best to try to update all the uses in tests that
just happened to use the old ones to the newer intrinsics.
I'm not sure I got all of the immediate operand conversions
correct, since the value seems to have been ignored by the
old pattern but I don't think it really matters.
