David Green	fb8c9a339a	[ARM] Use isFMAFasterThanFMulAndFAdd for scalars as well as MVE vectors This adds extra scalar handling to isFMAFasterThanFMulAndFAdd, allowing the target independent code to handle more folds in more situations (for example if the fast math flags are present, but the global AllowFPOpFusion option isnt). It also splits apart the HasSlowFPVMLx into HasSlowFPVFMx, to allow VFMA and VMLA to be controlled separately if needed.

[ARM] Use isFMAFasterThanFMulAndFAdd for scalars as well as MVE vectors

This adds extra scalar handling to isFMAFasterThanFMulAndFAdd, allowing
the target independent code to handle more folds in more situations (for
example if the fast math flags are present, but the global
AllowFPOpFusion option isnt). It also splits apart the HasSlowFPVMLx
into HasSlowFPVFMx, to allow VFMA and VMLA to be controlled separately
if needed.

[ARM] Fill in FP16 FMA patterns

This adds fp16 variants of all the fma patterns in the ARM backend.
