PR modula2/113836 gm2 does not dump gimple or quadruples to file

This patch provides the localized modula2 changes to gcc/m2
which facilitate the dumping of gimple and quadruples to file.
PR modula2/113836 will be full complete after a subsequent patch
adding changes to lang.opt and documentation.  The lang.opt
patch requires all language bootstrap regression testing whereas
this patch is isolated to gcc/m2 and only the m2 language.
