        Support two-lane vector BB reductions without target support

    we may vectorize gcc.target/i386/pr27827.c and gcc.target/i386/pr50038.c
    with -march=native and

    $ make check-gcc RUNTESTFLAGS="--target_board='unix{-m32\
-march=native,-march=native}'

    get

    FAIL: gcc.target/i386/pr27827.c scan-assembler fmul[ \t]*%st
    FAIL: gcc.target/i386/pr50038.c scan-assembler-times movzbl 2

    Since these 2 tests don't use SEE instructions originally, compile them
    with -mno-sse to avoid test failures.
