Yeah, sync_double_compare_and_swapdi_pic and
sync_double_compare_and_swap_ccdi_pic insns are a little bit register hungry,
they need %eax, %edx, %ecx and one of %esi or %edi.  %ebx is reserved for PIC
pointer, without -fomit-frame-pointer %ebp is reserved as well, %esp is
reserved, so only one of %esi and %edi is left for other stuff.
