Looks like this patch is already outdated by D85546 <https://reviews.llvm.org/D85546>, but thought I'd offer it anyway in case the framework help...
This patch is an attempt to lower fixed-width ZEXT by bitcasting the input to the result type, then AND'ing with an immediate that matches the input type.
