[committed] testsuite: Add -Wno-psabi -w to g++.dg/ext/builtin-shufflevector-1.C

[Jakub Jelinek]

Hi!

The testcase without this FAILs on i686-linux, where we warn about returning
of a generic vector changing the ABI:

Excess errors:
.../gcc/gcc/testsuite/g++.dg/ext/builtin-shufflevector-1.C:6:15: warning: SSE vector return without SSE enabled changes the ABI [-Wpsabi]
.../gcc/gcc/testsuite/g++.dg/ext/builtin-shufflevector-1.C:17:54: warning: SSE vector argument without SSE enabled changes the ABI [-Wpsabi]

Fixed thusly, tested on x86_64-linux (-m32,-m32/-mno-sse,-m64), committed to
trunk as obvious.
