    rs6000: Fix pr66144-3.c test to accept multiple equivalent insns. [PR115262]
    
    Jeff's commit r15-831-g05daf617ea22e1 changed the instruction we expected
    for this test case into an equivalent instruction.  Modify the test case
    so it will accept any of three instructions we could get depending on the
    options used.

            * gcc.target/powerpc/pr66144-3.c (dg-do): Compile for all targets.
            (dg-options): Add -fno-unroll-loops and remove -mvsx.
            (scan-assembler): Change from this...
            (scan-assembler-times): ...to this.  Tweak regex to accept multiple
            allowable instructions.
