[commit/Tru64] Ada tasking support on Tru64

[Joel Brobecker]

Hello,

Another tiny change - This is the target-specific part of Ada tasking
support on Tru64. Since I was looking at dec-threads, I figured I might
as well contribute this bit now.

2009-03-05  Joel Brobecker  <brobecker@adacore.com>

        Implement the target-specific part of Ada tasking support
        on Tru64.

        * dec-thread.c (dec_thread_get_ada_task_ptid): New function.
        (init_dec_thread_ops): Set the to_get_ada_task_ptid method.

Tested on alpha-tru64. Checked in.
