I think the problem with the old code was that we were using
a non-sibcall expander for an ECF_SIBCALL call. I.e. we generated
an insn that had the stack adjustment, was marked SIBLING_CALL_P,
and matched *sibcall_pop, but we generated it through call_pop
rather than (the nonexistent) sibcall_pop.
Perhaps I should instead have kept the calls.c support for
sibcall_pop and sibcall_value_pop and defined corresponding
expanders for x86.
