cmd/compile: only clobber dead slots at call sites We now have safepoints at nearly all the instructions. When GOEXPERIMENT=clobberdead is on, it inserts clobbers nearly at every instruction. Currently this doesn't work. (Maybe the stack maps at non-call safepoints are still imprecise. I haven't investigated.) For now, only use call-based safepoints if the experiment is on. Updates #27326. Change-Id: I72cda9b422d9637cc5738e681502035af7a5c02d Reviewed-on: https://go-review.googlesource.com/131956 Reviewed-by: Keith Randall <khr@golang.org>
