Add explicit VIS intrinsics for addition and subtraction. 

gcc/

	* config/sparc/sparc.c (sparc_vis_init_builtins): Add explicit
	builtins for VIS vector addition and subtraction.
	* config/sparc/visintrin.h (__vis_fpadd16, __vis_fpadd16s,
	__vis_fpadd32, __vis_fpadd32s, __vis_fpsub16, __vis_fpsub16s,
	__vis_fpsub32, __vis_fpsub32s): New.
	* doc/extend.texi: Document new VIS intrinsics.

gcc/testsuite/

	* gcc.target/sparc/fpaddsubi.c: New test.
