[PATCH] D34921: [ConstantHoisting] Remove dupliate logic in constant hoisting

[Leo Li via Phabricator via llvm-commits]

aoli added a comment.

if we call `isStaticAlloca` in `canReplaceOperandWithVariable` it is still possible to turn a constant-size stack allocation into a variable-size stack allocation in SimplifyCFG. Is that ok?
