Simon Pilgrim 9c3138bd6d [InstCombine] visitTrunc - pass through undefs for trunc(shift(trunc/ext(x),c)) patterns
Based on the recent patches D88475 and D88429 where we are losing undef values due to extension/comparisons.

I've added a Constant::mergeUndefsWith method that merges the undef scalar/elements from another Constant into a specific Constant.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
