2008-03-09  Ira Rosen  <irar@il.ibm.com>

	* config/rs6000/rs6000.c (builtin_description): Rename vector
	left shift operations.
	* config/rs6000/altivec.md (UNSPEC_VSL): Remove.
	(altivec_vsl<VI_char>): Rename to ...
	(ashl<mode>3): ... new name.
	(mulv4sf3, mulv4si3, negv4sf2): Replace gen_altivec_vslw with
	gen_ashlv4si3.
	(absv4sf2): Convert to use ashift:V4SI instead of UNSPEC_VSL.
