[InstCombine] avoid crash from deleting an instruction that still has uses (PR43723)
We gather a set of white-listed instructions in isAllocSiteRemovable() and then
replace/erase them. But we don't know in general if the instructions in the set
have uses amongst themselves, so order of deletion makes a difference.
There's already a special-case for the llvm.objectsize intrinsic, so add another
for llvm.invariant.end.
Should fix:
