testsuite: Fix up a few tests for i686-linux

Browse Source 
Some of these tests need -Wno-psabi to pass on ia32, forwprop-43.c
uses the vect* effective targets which rely on vect.exp added options
but doesn't provide those (added -msse2 for ia32).
And lastly, part-vect-absnegbf.c is a really weird test, it needs
at least -msse2 to pass on ia32 obviously (otherwise it is an error
to even use __bf16 or _Float16), but doesn't use -mavx512bf16 but
has avx512bf16 runtime check.  No idea what was meant, perhaps we
need 2 copies of the test, one with plain -msse2 and just requiring
sse2 at runtime and another wiht -mavx512bf16 requiring that?  Just
added -msse2 for now.

	* gcc.dg/tree-ssa/forwprop-42.c: Add -Wno-psabi to dg-options.
	* gcc.dg/tree-ssa/forwprop-43.c: Likewise.  For ia32 add -msse2 as
	dg-additional-options.
	* gcc.dg/torture/pr65270-3.c: Add -Wno-psabi to dg-options.
	* gcc.target/i386/part-vect-absnegbf.c: Add -msse2 to dg-options.
