  [NFC] Fix test for zext(shl(trunc)) fold (#113778)

This fold already exist but there is a call to [shouldChangeType
](https://github.com/llvm/llvm-project/blob/91fdfec263ff2b8e88433c4294a550cabb0f2314/llvm/lib/Transforms/InstCombine/InstCombineCasts.cpp#L1202)
that blocks it if the target layout is missing a definition of the types
in the casts.
