* add __cfi_slowpath_diag with a 3rd parameter which is a pointer to
the diagnostic info for the ubsan handlers.
*__cfi_check gets a 3rd parameter as well.
* unify vcall/cast/etc and icall diagnostic info format, and merge
the handlers to have a single entry point (actually two points due
to abort/noabort variants).
* tests
Note that this comes with a tiny overhead in the non-diag mode:
cfi_slowpath must pass 0 as the 3rd argument to cfi_check.

If user specifies aborting after a recoverable failed check is
appropriate, frontend should emit call to the _abort variant.
Test this behavior with newly added -fsanitize-recover flag.
