PR systemtap/1197
* loc2c.c (struct location): New members `fail', `fail_arg'.
(alloc_location): New function. Initialize those members.
(new_synthetic_loc, translate): Use that instead of obstack_alloc.
(location_from_address, location_relative): Likewise.
(FAIL): New macro. Use it everywhere in place of `error'.
(c_translate_location): Take new args FAIL, FAIL_ARG.
* loc2c.h: Update declaration.
* loc2c-test.c (fail): New function.
(handle_variable): Pass it to c_translate_location.
* tapsets.cxx (dwflpp::loc2c_error): New static method.
(dwflpp::literal_stmt_for_local): Pass it to to c_translate_location.
