Before this patch, non-capturingly parenthesized expressions with more
than one branch were processed incorrectly when part of a branch
followed by another branch. This patch fixes this by aligning the
handling of non-capturing parentheses with the handling of regular
parentheses.

* libgnat/s-regpat.adb
(Parse): Fix handling of non-capturing parentheses.
Tested on x86_64-pc-linux-gnu, committed on master.
