Keith Randall 7861aae155 cpu: pretend AVX-512 is disabled on Darwin ...

Darwin doesn't save/restore the AVX-512 mask registers when
processing a signal. Go generates lots of signals, which cause
the mask registers to randomly get clobbered. Better to pretend
that AVX-512 isn't supported.

Update golang/go#49233
