PR modula2/114648 cc1gm2 by default does not handle C pre-processor file and line...

This patch fixes the default behavior of cc1gm2 to the description in
the documentation.  By default cc1gm2 will allow C preprocessor
directives (they can be turned off via -fno-cpp).

gcc/m2/ChangeLog:

	PR modula2/114648
	* gm2-compiler/M2Options.mod (LineDirectives): Initially
	set to true.

gcc/testsuite/ChangeLog:

	PR modula2/114648
	* gm2/cpp/default/pass/AdvParse.def: New test.
	* gm2/cpp/default/pass/AdvParse.mod: New test.
	* gm2/cpp/default/pass/cpp-default-pass.exp: New test.
