modula2: tidyup remove unused procedures and unused parameters

This patch removes M2GenGCC.mod:QuadCondition and
M2Quads.mod:GenQuadOTypeUniquetok.  It also removes unused parameter
WalkAction for all FoldIf procedures.

gcc/m2/ChangeLog:

	* gm2-compiler/M2GenGCC.mod (QuadCondition): Remove.
	(FoldIfEqu): Remove WalkAction parameter.
	(FoldIfNotEqu): Ditto.
	(FoldIfGreEqu): Ditto.
	(FoldIfLessEqu): Ditto.
	(FoldIfGre): Ditto.
	(FoldIfLess): Ditto.
	(FoldIfIn): Ditto.
	(FoldIfNotIn): Ditto.
	* gm2-compiler/M2Quads.mod (GenQuadOTypeUniquetok): Remove.
