  Bug 7458: Trap arithmetic exceptions on Mac OS X

* sources/lib/run-time/llvm-exceptions.c
  (exception_port): New static variable.
  (catcher): New thread function for running mach_exc_server.
  (catch_mach_exception_raise, catch_mach_exception_raise_state): New
   dummy handler functions called by mach_exc_server.
  (catch_mach_exception_raise_state_identity): New Mach exception handler
   function for EXC_ARITHMETIC exceptions.
  (EstablishDylanExceptionHandlers): Implement by starting a server
   thread when needed and setting the current thread's exception port
   for EXC_ARITHMETIC to exception_port.
  (RemoveDylanExceptionHandlers): Edit commentary.

* sources/lib/run-time/Makefile.in: Add rules for running MIG (the
  Mach Interface Generator) to generate server interface codewhen
  building for Mac OS X. Build the generated mach_excServer.c source
  file into the LLVM run-time.
