amdgcn: Add ashlvNm, mulvNm macros

I need some extra shift varieties in the mode-independent code, but the macros
don't permit insns that don't have QI/HI variants.  This fixes the problem, and
adds the new functions for the follow-up patch to use.

gcc/ChangeLog:

	* config/gcn/gcn.cc (GEN_VNM_NOEXEC): Use USE_QHF.
	(GEN_VNM): Likewise, and call for new ashl and mul variants.

(cherry picked from commit f194924984c4eb9c8be5310f78b191b35e576ab8)
