[pushed] c++: array of PMF [PR113598]

[Jason Merrill]

Tested x86_64-pc-linux-gnu, applying to trunk.

-- 8< --

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.

gcc/cp/ChangeLog:

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

gcc/testsuite/ChangeLog:

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