rs6000: Fix PR67344
The "*and<mode>3_imm_dot_shifted" pattern is a define_insn_and_split,
like most "dot" patterns: if its output is not assigned cr0 but some
other cr reg, it splits to a non-dot insn and a compare.
Unfortunately that non-dot insn will clobber cr0 as well. We could
add another clobber (with "=X,x"), but then that second alternative
is never useful; instead, just remove that second alternative.
