Sanjay Patel 79c7fa31f3 [InstCombine] check alloc size in bitcast of geps fold (PR44321) ...

We missed a constraint in D44833
when folding a bitcast into a GEP with vector/array types.
If the alloc sizes specified by the datalayout don't match,
this could miscompile as shown in:
https://bugs.llvm.org/show_bug.cgi?id=44321
