Russ Cox 8ac23a1f15 runtime: document, clean up internal/sys
Document what the values in internal/sys mean.

Remove various special cases for arm64 in the code using StackAlign.

Delete Uintreg - it was for GOARCH=amd64p32,
which was specific to GOOS=nacl and has been retired.

This CL is part of a stack adding windows/arm64
support (#36439), intended to land in the Go 1.17 cycle.
This CL is, however, not windows/arm64-specific.
It is cleanup meant to make the port (and future ports) easier.
