[PATCH] D56810: [Mem2Reg] Enable promotion for bitcastable load/store values

[Sergey Dmitriev via Phabricator via llvm-commits]

We use this in the internal product based on LLVM. I am not changing existing PromoteMemToReg functionality, just extending it to allow alloca use-def chain to have GEPs with zero indices and bitcasts between alloca and dependent loads/stores as long as the load/store type is bitcastable to the allocated type. This could be beneficial for the common case as well.
