[PATCH] D57278: [Sanitizers] UBSan unreachable incompatible with ASan in the presence of `noreturn` calls

[Julian Lettner via Phabricator via cfe-commits]

Directly insert calls to `__asan_handle_no_return`

Clang-CodeGen now directly insert calls to `__asan_handle_no_return`
when a call to a noreturn function is encountered and both UBsan
unreachable and ASan are enabled. This allows UBSan to continue
removing the noreturn attribute from functions without any changes to
the ASan pass.
