[llvm-branch-commits] [llvm] [Passes] Disable code sinking in InstCombine early on. (PR #72567)

[Florian Hahn via llvm-branch-commits]

Sinking instructions very early in the pipeline destroys
dereferenceability information, that could be used by other passes, e.g.
this can prevent if-conversion by SimplifyCFG.
