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.

	PR c++/105187

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.
