These registers are not available for programs to use. Prior to this change, the compiler would crash attempting to use ZR as a general purpose register. Other programs would compile but on execution would overwrite the G register and cause havoc. Fixes linux/arm64 build. Fixes #10304 Fixes #10320 Change-Id: I5cf51d3b77cfe3db7dd6377324950cafb02f8d8b Reviewed-on: https://go-review.googlesource.com/8456 Reviewed-by: Minux Ma <minux@golang.org>
