c++: Handle multiple aggregate overloads [PR95319].
Here, when considering the two 'insert' overloads, we look for aggregate
conversions from the same initializer-list to B<3> or
initializer_list<B<3>>. But since my fix for reshape_init overhead on the
PR14179 testcase we reshaped the initializer-list directly, leading to an
error when we then tried to reshape it differently for the second overload.
gcc/cp/ChangeLog:
PR c++/95319
* decl.c (reshape_init_array_1): Don't reuse in overload context.
gcc/testsuite/ChangeLog:
PR c++/95319
* g++.dg/cpp0x/initlist-array12.C: New test.
