Fix FMA primops generating broken assembly on x86.

`genFMA3Code` assumed that we had to take extra precations to avoid overwriting
the result of `getNonClobberedReg`. One of these special cases caused a bug resulting
in broken assembly.

I believe we don't need to hadle these cases specially at all, which means this MR simply
deletes the special cases to fix the bug.

Fixes #24160

EPA: Remove parenthesizeHsType

This is called from PostProcess.hs, and adds spurious parens.
With the looser version of exact printing we had before we could
tolerate this, as they would be swallowed by the original at the same
place.

But with the next change (remove EpAnnNotUsed) they result in
duplicates in the output.

For Darwin build:

Add name for -Wdeprecated-type-abstractions (#24154)

This warning had no name or flag and was triggered unconditionally.
Now it is part of -Wcompat.

EPA: Remove EpAnnNotUsed

We no longer need the EpAnnNotUsed constructor for EpAnn, as we can
represent an unused annotation with an anchor having a EpaDelta of
zero, and empty comments and annotations.

This simplifies code handling annotations considerably.
