[PATCH] s390: Fix builtin-classify-type-1.c on s390 too [PR112725]

[Jakub Jelinek]

Hi!

Given that the s390 backend defines pretty much the same target hook
as rs6000, I believe it suffers (at least when using -mvx?) the same
problem as rs6000, though admittedly this is so far completely
untested.

Ok for trunk if it passes bootstrap/regtest there?

	* config/s390/s390.cc (s390_invalid_arg_for_unprototyped_fn): Return
	NULL for __builtin_classify_type calls with vector arguments.

Now successfully bootstrapped/regtested on s390x-linux and indeed it
fixes
-FAIL: c-c++-common/builtin-classify-type-1.c  -Wc++-compat  (test for excess errors)
-UNRESOLVED: c-c++-common/builtin-classify-type-1.c  -Wc++-compat  compilation failed to produce executable
there as well.
