Dmitri Shuralyov	1bfbee0e20	all: update go directive to 1.18 Done with: go get go@1.18 go mod tidy go fix ./... Using go1.21.3. Also update code generators to use only the new go:build lines, not the old +build ones. For golang/go#60268.

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.

Vaughn Iverson	b677753862	cpu: fix AVX512 support detection on Darwin Summary: On darwin/amd64, it is not adequate to use OSXSAVE bits to determine AVX512 availabilty. The reason is involved. See github issue for details. The fix consists of implementing Apple's recommended approach using the process commpage cpu_capabilities bits to determine availability of AVX512.

Andreas Auernhammer	4adea008a5	cpu: new package This CL introduces a new cpu package for CPU/platform feature detection. The cpu package is basically a copy of `internal/cpu` of the standard library. Revision: bf86aec25972f3a100c3aa58a6abcbcc35bdea49 This CL does not export ARM64 and PPC64 feature detection since at the moment ARM64/PPC64 requires standard library support.
