cmd/compile/internal/ssa: cleanup ANDCCconst rewrite rules on PPC64
Avoid creating duplicate usages of ANDCCconst. This is preparation for
a patch to reintroduce ANDconst to simplify the lower pass while
treating ANDCCconst like other *CC* ssa opcodes.
Also, move many of the similar rules wich retarget ANDCCconst users
to the flag result to a common rule for all compares against zero.
