	Backport rs6000 changes from GCC 4.5 mainline to 4.3 that fixes
	some problems that show up with vectorization.

PR tree-optimization/40219
	* tree.c (iterative_hash_expr): Make sure the builtin function is
	a normal builtin function and not a front end or back end builtin
	before indexing into the built_in_decls array.

PR tree-optimization/40049
	* tree-vect-transform.c (vectorizable_operation): If the machine
	has only vector/vector shifts, convert the type of the constant to
	the appropriate type to avoid building incorrect trees, which
	eventually have problems with garbage collection.
