	gdb/ChangeLog
	* valarith.c (value_vector_widen): New function for replicating a
	scalar into a vector.
	(value_binop): Use value_vector_widen to widen scalar to vector
	rather than casting, this better matches gcc C behaviour.
	* valops.c (value_casst): Update logic for casting between vector
	types, and for casting from scalar to vector, try to match gcc C
	behaviour.
	* value.h (value_vector_widen): Declare.
	* opencl-lang.c (opencl_value_cast): New opencl specific casting
	function, handle special case for casting scalar to vector.
	(opencl_relop): Use opencl_value_cast.
	(evaluate_subexp_opencl): Use opencl_value_cast instead of
	value_cast, and handle BINOP_ASSIGN, UNOP_CAST, and UNOP_CAST_TYPE
	in order to use opencl_value_cast.
	
	gdb/testsuite/ChangeLog
	* gdb.base/gnu_vector.c: New variable for use in tests.
	* gdb.base/gnu_vector.exp: Update and extend tests to reflect
	changes in scalar to vector casting and widening.
	* gdb.python/py-type.c: New variables for use in tests.
	* gdb.python/py-type.exp: Update vector related tests to reflect
	changes in scalar to vector casting and widening.
