[PATCH] D34576: [ConstantHoisting] Avoid hoisting constants in GEPs that index into a struct type.

[Leo Li via Phabricator via llvm-commits]

aoli added a comment.

@ributzka it seems that it is guaranteed that the indices into struct type must be constants. It is not only being used by  AddressingModeMatcher. It is also being used by  lib/IR/Instructions.cpp:getIndexedTypeInternal. We don't want to break this guarantee so that we want to fix the constant hoisting.
