kvx: O_pseudo_fixup

kvx: O_pseudo_fixup

O_pseudo_fixup was defined as O_max+1, missing the fact that O_md1
through O_md32 enums are for use by target code.  Worse, kvx-parse.c
used 64 rather than O_pseudo_fixup.  Fix this, and wrap some overlong
lines.

	* config/tc-kvx.h (O_pseudo_fixup): Define.
	* config/tc-kvx.c (O_pseudo_fixup): Don't define here.
	(insert_operand): Delete bogus comment and cast.
	* config/kvx-parse.c (promote_token): Use O_pseudo_fixup
	rather than hardcoded value.  Wrap overlong lines.
	(get_token_class): Likewise.
	(parse_with_restarts): Wrap overlong line.
