LOG: [CLANG] XFAIL c-strings.c & volatile-1.c AArch64/Windows

c-strings.c was marked XFAIL for msvc ABI on AArch64/Windows platform.
But it is failing due to alignment issue on WoA for both msvc and gnu
gnu ABIs. I am going to mark them as XFAIL for both.

LOG: Revert "[InstCombine] Treat passing undef to noundef params as UB"

This reverts commit c911befaec494c52a63e3b957e28d449262656fb.

It has broken LLDB Arm/AArch64 Linux buildbots. I dont really understand
the underlying reason. Reverting for now make buildbot green.

This test is again failing across multiple bots and passing on others
there is no reliable way to enable it for some of the bots while

This test has started passing consistently on 32bit arm where underlying
