There are tests for the `__builtin_verbose_trap` builtin, which was the only way Clang used to emit the artificial frames for LLDB to recognize. After https://github.com/llvm/llvm-project/pull/145967 we now also emit those fake frames for `ubsan` traps. The test added here ensures the UBSAN traps get recognized by LLDB
