c++: ICE with -fno-exceptions and array init [PR107198]
The removed line no longer has an effect on anew5.C error recovery, and
removing it improves error recovery for this testcase.
PR c++/107198
gcc/cp/ChangeLog:
* typeck2.cc (process_init_constructor_array): Use VEC_INIT_EXPR
regardless of seen_error.
gcc/testsuite/ChangeLog:
* g++.dg/eh/no-exceptions1.C: New test.
