[PATCH] D63946: [TSan] Improve handling of stack pointer mangling in {set,long}jmp, pt.4

[Julian Lettner via Phabricator via llvm-commits]

yln added a comment.

I reverted this, because we are doing a call (`%rsi` is not a preserved register), so of course we have to save/restore it (even if we don't clobber it ourselves).
