[patch] gcse.c: Remove an obsolete comment.

[Kazu Hirata <kazu at cs dot umass dot edu>]

Hi,

Attached is a patch to remove an obsolete comment.

These days it shouldn't hurt to create small helper functions as they
are likely to be inlined, especially if they are called only in one
place.

OK to apply?
