[PATCH] modula-2: Handle pass '-v' option to the compiler.

[Iain Sandoe]

Tested on x86-64-darwin21.
OK for trunk?

Somehow this setting had been missed, and we really need the verbose
flag to enable useful debug output.

Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>

gcc/m2/ChangeLog:

	* gm2-gcc/m2options.h (M2Options_SetVerbose): Export the
	function.
	* gm2-lang.cc: Handle OPT_v, passing it to the compiler.
	* lang-specs.h: Pass -v to cc1gm2.
