[COMMITTED] ada: Fix gnatmake's parsing of adc files

[Marc Poulhiès via Gcc-patches]

From: Ronan Desplanques <desplanq...@adacore.com>

Before this patch, gnatmake's parser for adc files failed to ignore
semicolons located inside comments. This patch fixes that behavior.

gcc/ada/

        * sfn_scan.adb (Scan_SFN_Pragmas): Improve handling of comments.

Tested on x86_64-pc-linux-gnu, committed on master.
