I think Richi also wanted the
gimple_code (stmt) == GIMPLE_CALL
Turned into:
is_gimple_call (stmt)
Presumably using chkp_gimple_call_builtin_p rather than
gimple_call_builtin_p is related to using different codes for the
instrumented builtin calls? Otherwise why use
chkp_gimple_call_builtin_p rather than gimple_call_builtin_p?
