[COMMITTED] ada: Change Present_Expr field type to Uint

[Marc Poulhiès via Gcc-patches]

From: Richard Kenner <ken...@adacore.com>

We want the field to be initialized to No_Uint because we want to be
able to test in GNAT LLVM whether we've already set it so we can be
sure we only set it once.

gcc/ada/

        * gen_il-gen-gen_nodes.adb (Present_Expr): Type is now Uint.

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