        x86 SSE: Improved vector initialization/construction.
    
    improved vector initialization/construction.  But some tests failed with
    SSE3.  For expample, with SSE3, we generate better codes:
    
    fmm:
            movddup m(%rip), %xmm0
            ret
    
    than with SSE2:
    
    fmm:
            movsd   m(%rip), %xmm0
            unpcklpd        %xmm0, %xmm0
            ret
    
    for fmm in gcc.target/i386/sse2-init-v2df-1.c.  Replace -mno-sse4.1 with
    -mno-sse3 to disable SSE3 in these tests.
    
            * gcc.target/i386/sse2-init-v2df-1.c: Replace -mno-sse4.1 with
            -mno-sse3.
            * gcc.target/i386/sse2-init-v2df-2.c: Likewise.
            * gcc.target/i386/sse2-init-v2di-3.c: Likewise.
            * gcc.target/i386/sse2-init-v2di-4.c: Likewise.
