Hi Hans,

Could you please cherry pick these two commits into the release-10 branch:


They're reverts of the work in https://reviews.llvm.org/D68945 that turned out
to be half baked, and breaks debug information for -fsanitize=safe-stack, as
reported in bug 44585. Crucially, incorrect locations under safestack are being
generated even at -O0, which is a fairly bad failure.

For a clean merge, these commits depend on the cherry pick in bug 44814. This
is due to a spurious test conflict; I can separate the two if needs be.

Thanks for all the release engineering!
