[x86] add tests to show potential opt-out of ftrunc optimization; NFC

This is another preliminary step for disabling this transform as
discussed in the post-commit thread for:
rL330437
I'm using one of the names suggested there for the attribute, but
we can fix that up as needed once the clang side of this is sorted
out.
