    c++: vector compound literal [PR105187]
    
    My cleanup in r12-296 cleared TREE_HAS_CONSTRUCTOR on digested class
    initializers, but we leave it set for vectors, since we can't wrap them in
    TARGET_EXPR.

    gcc/cp/ChangeLog:
    
            * typeck2.cc (store_init_value): Allow TREE_HAS_CONSTRUCTOR for
            vectors.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.c-torture/compile/20050113-1.c: Moved to...
            * c-c++-common/torture/20050113-1.c: ...here.
