[PATCH INSTALLED]: Fix MPC buglet in rounding type.

Minor gnit in the MPC code, we need two separate rounding types.  One is
the MPFR style type and one is the MPC style type, each is used in
different function calls depending on what type of variable we're
operating on.

Tested with MPC active, no regressions.

Installed on mainline as "obvious".
