target/arm: Handle FPCR.AH in negation in FMLS (vector)
Handle the FPCR.AH "don't negate the sign of a NaN" semantics
in FMLS (vector), by implementing a new set of helpers for
the AH=1 case.
The float_muladd_negate_product flag produces the same result
as negating either of the multiplication operands, assuming
neither of the operands are NaNs. But since FEAT_AFP does not
negate NaNs, this behaviour is exactly what we need.
