Daniel Sanders a61aa38ee1 [mips][mips64r6] madd.[ds], msub.[ds], nmadd.[ds], and nmsub.[ds] are not available on MIPS32r6/MIPS64r6
Summary:
This patch updates both the assembler and the code generator.

MIPS32r6/MIPS64r6 replaces them with maddf.[ds] and msubf.[ds] which are fused
multiply-add/sub operations. We don't emit these yet, this patch only prevents the removed instructions from being emitted.

Depends on D3955
