[PATCH] D75967: Work around somes register/spill/liveness issues relating to returnTwice aka setjmp

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Was digging around for something else and happened to spot this.

Since this was posted, https://reviews.llvm.org/D77767 made a similar change to RegisterCoalescer.

InlineCost.cpp already has a check for ReturnsTwice.

Maybe worth taking another look at the change to StackColoring.
