    testsuite: vect: ppc: skip pr112325.c without vsx
    
    These two test variants hit the same problems on powerpc-elf with
    altivec without vsx: we can't vectorize the loops for various reasons.
    We need the peeling, we need strict-align disabled to inline memcpy,
    we need vect_widen_mult_qi_to_hi, but even with that, we fail to
    vectorize due to unsupported vector widening conversions.
    
    Extend the peeling param to all powerpc targets, but skip the test
    when vsx is not available.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/vect/pr112325.c: Bump the peeled-insns count on all
            powerpc targets.  Skip the test on powerpc without vsx.
            * gcc.dg/vect/pr117888-1.c: Likewise.
