i386: Refactor new ix86_expand_carry to set the carry flag.
This patch refactors the three places in the i386.md backend that we
set the carry flag into a new ix86_expand_carry helper function, that
allows Jakub's recently added uaddc<mode>5 and usubc<mode>5 expanders
to take advantage of the recently added support for the stc instruction.
