[InstSimplify] Fix poison safety in insertvalue fold
We can only fold insertvalue undef, (extractvalue x, n) to x

[InstSimplify] Fix poison safety in insertvalue fold
We can only fold insertvalue undef, (extractvalue x, n) to x
if x is not poison, otherwise we might be replacing undef with
poison (https://alive2.llvm.org/ce/z/fnw3c8). The insertvalue
poison case is always fine.
I didn't go to particularly large effort to preserve cases where
folding with undef is still legal (mainly when there is a chain of
multiple inserts that end up covering the whole aggregate),
because this shouldn't really occur in practice: We should always
be generating the insertvalue poison form when constructing
aggregates nowadays.
