[Clang] Trap reasons null check

As of current, a null check is in place for emitting trap reasons via the `-fsanitize-trap=` flag (trap reasons can be disabled with `-fno-sanitize-debug-info-traps`). This is to prevent a nullptr dereference since clang will sometimes emit a UBSan trap into the prologue of a function when debug-info locations aren't defined.
Test case here with more details:
`clang/test/CodeGen/ubsan-trap-reason-crash.cpp`.
[not upstream yet, will edit this line out once upstream]
