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.
