[PATCH] Make gt_pch_nx unreachable in symbol-summary classes.

[Martin Liška]

Hello.

For the symbol/call summary we don't expect that it will be streamed
for PCH purpose. So that, I would like to mark all gt_pch_nx functions
with gcc_unreachable.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

	* symbol-summary.h (gt_pch_nx): Mark all functions
	with gcc_unreachable as we do not expect to be called.
