[PATCH 2/5] match.pd: Remove commented out line pragmas unless -vv is used.

Hi All,

genmatch currently outputs commented out line directives that have no effect
but the compiler still has to parse only to discard.

They are however handy when debugging genmatch output.  As such this moves them
behind the -vv flag.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Ok for master?

Thanks,
Tamar

gcc/ChangeLog:

	PR bootstrap/84402
	* genmatch.cc (output_line_directive): Only emit commented directive
	when -vv.
	(main): Initialize verbose.
