I see FAILs on i686-linux or on x86_64-linux (in the latter
with -m32 testing).

One problem is that vector-10.c doesn't use -Wno-psabi option
and uses a function which returns a vector and takes vector
as first parameter, the other problems are that 3 other
tests don't arrange for at least basic vector ISA support,
plus non-standardly test only on x86_64-*-*, while normally
one would allow both i?86-*-* x86_64-*-* and if it is e.g.
specific to 64-bit, also check for lp64 or int128 or whatever
else is needed.  E.g. Solaris I think has i?86-*-* triplet even
for 64-bit code, etc.

The following patch fixes these.

	* gcc.dg/tree-ssa/satd-hadamard.c: Add -msse2 as dg-additional-options
	on x86.  Also scan-tree-dump on i?86-*-*.
	* gcc.dg/tree-ssa/vector-8.c: Likewise.
	* gcc.dg/tree-ssa/vector-9.c: Likewise.
	* gcc.dg/tree-ssa/vector-10.c: Add -Wno-psabi to dg-additional-options.
