	* gcc.c-torture/execute/simd-1.c: New.
	
	* gcc.dg/simd-1.c: New.
	
	* doc/extend.texi (Vector Extensions): Document that we can
	specify simd types not specifically supported by the hardware.
	Document that simd types can be used as function arguments.
	Document that signness does make a difference in SIMD types.
	Misc cleanups and revisions to the "vector extensions" section.
	
	* simplify-rtx.c (simplify_subreg): Simplify subregs of vector
	constants.
	
	* expr.c (vector_mode_valid_p): New.
	
	* expr.h: Add vector_mode_valid_p.
	
	* defaults.h (VECTOR_MODE_SUPPORTED_P): Set default.
	
	* emit-rtl.c (immed_double_const): Do not abort on vectors.
	
	* c-common.c (type_for_mode): Always build vector nodes regardless
	of VECTOR_MODE_SUPPORTED_P.
	(handle_mode_attribute): Error if we can't emulate a nonexisting
	vector mode.
	(handle_vector_size_attribute): Same.
	
	* optabs.c (expand_binop): Open-code vector operations.
	(expand_unop): Open-code vector unops.
	(expand_vector_binop): New.
	(expand_vector_unop): New.
	
	* c-typeck.c (build_binary_op): Allow vectors in binops.
	Allow vectors in conditional operatiors.
