Here AGGREGATE_TYPE_P includes pointers to member functions, which is not
what we want.  Instead we should use class||array, as elsewhere in the
function.

PR c++/113598

gcc/cp/ChangeLog:

* init.cc (build_vec_init): Don't use {} for PMF.

gcc/testsuite/ChangeLog:

* g++.dg/cpp0x/initlist-pmf2.C: New test.

(cherry picked from commit 136a828754ff65079a834555582b49d54bd5bc64)
