c++: array of PMF [PR113598]

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.
