Russ Cox 5ea612d1eb all: go fmt ./... 
Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).

Not strictly necessary but will avoid spurious changes
as files are edited.

Part of //go:build change (#41184).
See https://golang.org/design/draft-gobuild

Tamir Duberstein be400aefbc all: build tags: appengine,!gccgo => purego,gc 
appengine is obsolete and superseded by purego, and gc is a more

Filippo Valsorda 37a17fe027 internal/subtle: add Any/InexactOverlap (new package) and apply them across packages 
AnyOverlap and InexactOverlap implement checks for the aliasing
requirements defined by the crypto/cipher interfaces. Apply them to all
implementations as the actual requirement could be architecture-dependent
and user code should not rely on undefined behavior.

Updates golang/go#21624

SP offsets were adjusted to fill in the now unused callee save area
using the following Python script:

import sys, re

    if delta >= 408:
        delta -= (408 - 352)
    return "%d(SP)" % delta

The spadj computation in the assembler can't handle SP alignment code
and will just get confused by how it's currently written. Do the
alignment in a scratch register to hide it from the assembler.
