I've submitted a PR, https://bugs.llvm.org/show_bug.cgi?id=47296, regarding the debuginfo problem.

For know I simply hardcoded a condition to avoid the transform downstream for out target (when vectors are involved), as a workaround to the problem with now having any simple way to lower a vector zext.
