    rtl-optimization/110869 Fix tests cmp-mem-const-*.c for sparc

    This fixes the rather new tests cmp-mem-const-{1,2,3,4,5,6}.c for sparc.
    For -1 and -2 we need at least optimization level 2 on sparc.  For the
    sake of homogeneity, change all test cases to -O2.  For -3 and -4 we do
    not end up with a comparison of memory and a constant, and finally for
    -5 and -6 the constants are reduced by a prior optimization which means
    there is nothing left to do.  Thus excluding sparc from those tests.
