modula2: Add noreturn attribute to m2/gm2-libs/M2RTS.mod

This patch removes a build warning by adding a noreturn attribute
to the M2RTS.mod:HaltC procedure.  Also add an infinite loop to
gm2-libs-min/M2RTS.mod.

gcc/m2/ChangeLog:

	* Make-lang.in (m2/gm2-libs-boot/M2RTS.o): Remove
	--suppress-noreturn.
	* gm2-libs/M2RTS.mod (HaltC): Add noreturn attribute.
	* gm2-libs-min/M2RTS.mod (HALT): Add LOOP END.
