match: Fix comment for X != 0 ? X + ~0 : 0 transformation

Browse source 
Just a small coment fix, the `(` was in the wrong location,
making it look it was transforming into `(X - X) != 0`
rather than `X - (X != 0)`.

Pushed as obvious after a quick build for x86_64-linux-gnu.

gcc/ChangeLog:

	* match.pd (X != 0 ? X + ~0 : 0): Fix comment.
