[PATCH] D118538: [SLP] Schedule only sub-graph of vectorizable instructions

[Arthur Eubanks via Phabricator via llvm-commits]

Hi, we've bisected some win32 miscompiles to this patch: https://crbug.com/1300322.
It seems like some inalloca allocas are getting moved around relative to their corresponding llvm.stacksave/stackrestore.
Not being familiar with SLPVectorizer, I'm not sure if this patch caused it or exposed some existing issue. Any advice?
