10 daystarget/arm: Implement FMOPA (non-widening) for fp16Peter Maydell4-0/+63

10 daystarget/arm: Support FPCR.AH in SME FMOPS, BFMOPSRichard Henderson4-33/+161
For non-widening, we can use float_muladd_negate_product, For widening, which uses dot-product, we need to handle the negation explicitly.

10 daystarget/arm: Rename BFMOPA to BFMOPA_wPeter Maydell4-5/+5
Our current BFMOPA opcode pattern is the widening version of the insn. Rename it to BFMOPA_w, to make way for the non-widening version added in SME2.

10 daystarget/arm: Rename FMOPA_h to FMOPA_w_hPeter Maydell4-6/+6
The pattern we currently have as FMOPA_h is the "widening" insn that takes fp16 inputs and produces single-precision outputs. This is unlike FMOPA_s and FMOPA_d, which are non-widening produce outputs the same size as their inputs. SME2 introduces a non-widening fp16 FMOPA operation; rename FMOPA_h to FMOPA_w_h (for 'widening'), so we can use FMOPA_h for the non-widening version, giving it a name in line with the other non-widening ops FMOPA_s and FMOPA_d.
