re PR c++/34914 (Member pointer to vector rejected)

Browse Source 
PR c++/34914
	* c-common.c (handle_vector_size_attribute): Only allow
	integral, scalar float and fixed point types.  Handle OFFSET_TYPE
	the same way as pointer, array etc. types.
	* tree.c (reconstruct_complex_type): Handle OFFSET_TYPE.

	* g++.dg/ext/vector10.C: New test.
