code review 69020044: cmd/5a, cmd/5c, cmd/6a, cmd/6c, cmd/8a, cmd/8c, cmd/cc:...

cmd/5a, cmd/5c, cmd/6a, cmd/6c, cmd/8a, cmd/8c, cmd/cc: support for Native Client

From the original description in CL 15770043

The main change here is to consult $GOARCH.

In 6c, when GOOS=nacl, some of the more complex addressing modes must be disabled, and the BP and R15 registers must not be used.

See golang.org/s/go13nacl for design overview.

This CL appears to have broken the windows-amd64 builder.
