c++: ICE-on-invalid with designated initializer [PR106983]
We ICE in the code added in r12-7117: type_build_dtor_call gets
the error_mark_node because the type of 'prev' wasn't declared.
PR c++/106983
gcc/cp/ChangeLog:
* typeck2.cc (split_nonconstant_init_1): Check TYPE_P.
gcc/testsuite/ChangeLog:
* g++.dg/other/error36.C: New test.
