Problem with deprecated_select_gdbarch_hack

Mark,

   The current mainline gdb fails for ia64 linux due to an assertion in 
deprecated_select_gdbarch_hack().  I noticed you added this code recently.  I 
have attached a scripted session with set debug arch 1.  Can you verify if the 
debug messages indicate any unanticipated path through your code?  I am just 
trying to debug a simple "hello world" program.

I noticed it too. The gdb_assert() in deprecated_select_gdbarch_hack()
is faulty because gdbarch_update_p() does not necessarily change the
current gdbarch to the one passed to deprecated_select_gdbarch_hack().
It can leave the gdbarch unchanged if it's semantically equivalent to
the one asked to change to. Removal of the faulty gdb_assert() should
do the trick.

I have recently checked in a change to the ia64-tdep.c code to modernize it to 
grab the osabi from the gdbarch_info parameter and to call 
gdbarch_list_lookup_by_info() to look for existing gdbarch candidates.  This 
fixes the problem without having to remove the assertion.  Perhaps leaving the 
assertion will point out any existing platforms that use the older code ia64 was 
formerly using.
