cmd/internal/obj/arm: support more ARM VFP instructions
Add support of more ARM VFP instructions in the assembler.
They were introduced in ARM VFPv4.
"FMULAF/FMULAD Fm, Fn, Fd": Fd = Fd + Fn*Fm
"FNMULAF/FNMULAD Fm, Fn, Fd": Fd = -(Fd + Fn*Fm)
"FMULSF/FMULSD Fm, Fn, Fd": Fd = Fd - Fn*Fm
"FNMULSF/FNMULSD Fm, Fn, Fd": Fd = -(Fd - Fn*Fm)
The multiplication results are not rounded.
