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.

Keith Randall	6f8348627a	unix: fix darwin pipe implementation ... The raw syscall returned the two pipes whereas the libc call takes a pointer to a location to write the two pipes. When we switched over from raw syscalls to libc calls, this change in behavior was missed.
