    Constfold insertelement to undef when index is out-of-bounds

    This patch adds constant folding of insertelement instruction to undef
value when index operand is constant and is not less than vector size or is

    InstCombine does not support this case, but I'm happy to add it there also
if this change is accepted.

    Test Plan: Unittests and regression tests for ConstProp pass.
