Thanks for the speedy fix. This fixed vicmp, but vfcmp still fails for me
(r53241):

define <4 x i32> @test(i32 %argc, i8** %argv) {
entry:  
        %foo = vfcmp ueq <4 x float> <float undef, float undef, float undef,
float undef>, <float undef, float undef, float undef, float undef>
        ret <4 x i32> %foo
}

opt -instcombine crashes in the same spot.
