[PATCH] Share the "multi_line" helper among all Ada testcases

[Pierre-Marie de Rodat <derodat at adacore dot com>]

Hello,

This patch is a tiny cleanup for the Ada testsuite: it put the 
"multi_line" helper (currently defined in 6 testcases) in a common 
place: ada.exp. It triggers no regression (tested on x86_64-linux).

Ok to push?
Thank you in advance,
