The splitter for ashdi3_extswsli_dot for cr0 with memory uses emit_insn
gen_ashdi3_extswsli_dot, which does not work because that emits a scratch,
while the splitter runs after reload so there should be a real register
instead. We can laboriously fix that up, or emit using
gen_ashdi3_extswsli_dot2 instead. This patch does the latter.
