cris: Enable movhi and movqi to set condition codes. Anonymize.

Like with movsi_internal.  Looks like the "cc" attribute didn't
need tweaking for "movhi", but did for "movqi".  N.B.: disabled
alternatives make cause a later alternative to match.

Also, non-anonymous insns get declarations and gen_* functions.
We don't want that; even if it doesn't affect generated code
it's sloppy.  (This may or may not be preferable to the
name decorations obfuscating standard pattern names.)

Also anonymize left-over non-anonymous branches; they haven't
been needing names since the cbranch pattern was made the
generic method.

gcc:
	* config/cris/cris.md ("anz", "anzvc", "acc"): New define_subst_attrs.
	("<acc><anz><anzvc>movhi<setcc><setnz><setnzvc>"): Rename from
	"movhi".  Rename "cc" attribute to "cc<cccc><ccnz><ccnzvc>".
	("<acc><anz><anzvc>movqi<setcc><setnz><setnzvc>"): Similar from
	"movqi".  Correct contents of, and rename "cc" attribute to
	"cc<cccc><ccnz><ccnzvc>".
	("*b<zcond:code><mode>"): Rename from "b<zcond:code><mode>".
	("*b<nzvccond:code><mode>"): Rename from "b<nzvccond:code><mode>".
