Elliott Hughes 591a2a798d Remove obsolete hacks for the fabs() family.
We don't support GCC any more, and clang's got better since this commit
was written. It doesn't produce _identical_ code, but it's a similar
single-instruction bit twiddle.

This also doesn't regress x86 for fabsl (that code looks the same before
and after) and there is no riscv32.

Test: llvm-objdump -d
