[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.
