riscv: thead: Add support for the XTheadMac ISA extension
The XTheadMac ISA extension provides multiply-accumulate/subtract
instructions:
* mula/mulaw/mulah
* muls/mulsw/mulsh
To benefit from middle-end passes, we expand the following named
patterns in riscv.md (as they are not T-Head-specific):
* maddhisi4
* msubhisi4
