testsuite: Fix up pr110915* tests on i686-linux [PR110915]

These tests FAIL on i686-linux, with
.../gcc/testsuite/gcc.dg/pr110915-1.c:8:1: warning: MMX vector return without MMX enabled changes the ABI [-Wpsabi]
.../gcc/testsuite/gcc.dg/pr110915-1.c:7:15: warning: MMX vector argument without MMX enabled changes the ABI [-Wpsabi]
excess warnings.  I've added -Wno-psabi to quiet that up, plus I think
it is undesirable to define macros like vector before including C library
headers in case the header would use that identifier in non-obfuscated
form somewhere.

2023-09-01  Jakub Jelinek  <jakub@redhat.com>

	PR tree-optimization/110915
	* gcc.dg/pr110915-1.c: Add -Wno-psabi to dg-options.  Move vector
	macro definition after limits.h inclusion.
	* gcc.dg/pr110915-2.c: Likewise.
	* gcc.dg/pr110915-3.c: Likewise.
	* gcc.dg/pr110915-4.c: Likewise.
	* gcc.dg/pr110915-5.c: Likewise.
	* gcc.dg/pr110915-6.c: Likewise.
	* gcc.dg/pr110915-7.c: Likewise.
	* gcc.dg/pr110915-8.c: Likewise.
	* gcc.dg/pr110915-9.c: Likewise.
	* gcc.dg/pr110915-10.c: Likewise.
	* gcc.dg/pr110915-11.c: Likewise.
	* gcc.dg/pr110915-12.c: Likewise.
