Add a new frontend option (called `-trap-function <name>`, similar to Clang’s existing `-ftrap-function`) that specifies a function to call instead of trapping. When the option is used, the compiler will emit a call to the specified function every time it would have otherwise emitted a trap instruction. The function must have no parameters and it must never return. rdar://89125883
