[Bug target/38015] Converting between int and vector using intrinsics goes through memory

I think it depends on the tuning of the processor which decides if it should
goto memory or not.  -mtune=generic makes it go through memory while
-mtune=core2 does not and we get:
        movd    %edi, %xmm0
        paddd   LC0(%rip), %xmm0
        movd    %xmm0, %eax
        ret

Note I checking with -fPIC turned on.
