[RISCV] Don't promote f16 FNEG/FABS with Zfhmin/Zhinxmin. (#106474)
fneg/fabs are not supposed to canonicalize nans. Promoting to f32 will
go through an fp_extend which will canonicalize. The generic Promote
handler needs to be removed from LegalizeDAG.
We need to use integer bit manip to clear the bit instead.
Unfortunately, this is going through the stack due to i16 not being a
legal type. Fixing that will require custom legalization or some other
generic SelectionDAG change.
