[COMMITTED 51/51] ada: Reject misalignment of objects with address clause

[Marc Poulhiès]

From: Eric Botcazou <ebotca...@adacore.com>

Misaligned objects are meant to be rejected universally by the compiler.

gcc/ada/ChangeLog:

        * gcc-interface/decl.cc (gnat_to_gnu_entity) <E_Variable>: Validate
        a known alignment on the object even if there is an address clause.

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