        PR target/37434:
        * config/i386/i386.c (ix86_expand_vector_init_interleave): Force
        the even element into register.
        (ix86_expand_vector_init_general): Don't use
        ix86_expand_vector_init_interleave on V16QImode and V8HImode
        if we can't move from GPR to SSE register directly.
