    omit frame pointer in pr89676
    
    This i386 test expects only two movl instructions.
    
    In configurations that --enable-frame-pointer, -O2 won't implicitly
    enable -fomit-frame-pointer, so we end up with a third movl to set up
    the frame pointer.
    
    This patch enables -fomit-frame-pointer explicitly, so that the result
    no longer depends on that configuration option.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/i386/pr89676.c: Add -fomit-frame-pointer.
