[Ada] array and bounds in fat pointer can be a stub
This patch adds handling of the case when a fat pointer has the
P_ARRAY and/or P_BOUNDS fields defined as a stub. In that case,
this stub needs to be resolved.
There are two issues:
. First, making sure that the resolution takes place itself.
That's the change to ada_check_typedef.
. Make sure that the type returned after resolution is not itself
a typedef. This is the change to ada_check_typedef.
gdb/ChangeLog (Jerome Guitton, Joel Brobecker):
* ada-lang.c (desc_bounds): Add handling of the case where
the P_BOUNDS field is a pointer to a stub.
(desc_data_target_type): Same for P_ARRAY field.
(ada_check_typedef): Strip the typedef layers from the type
found by ada_find_any_type.

[Ada] Do not compute task ptid when debugging core file
After thread support over core files was added for GNU/Linux was added,
we started noticing the following type of crash when trying to perform
task switches (this is a bit accademic, since task switching is not
supported when debugging core files - this is what our testcase was
verifying).
(please check out the comment inside ada-tasks.c:task_command for
more details on this topic)
The reason for the crash comes from the fact that the GNU/Linux thread
layer now gets pushed on the target stack, causing the associated
to_get_ada_task_ptid target method to be activated. This routine
makes the assumption that, for all threads, the private area is not
NULL. This is incorrect in the case of core files, as the core layer
creates some threads with no private data.
But, taking a step back, we don't need to try to compute the task ptid,
as we'll never be using it anyways (we only use it for task switching).
So the fix is to avoid the ptid computation altogether when debugging
a core file.
gdb/ChangeLog:
* ada-tasks.c (read_atcb): Do not compute the task ptid when
debugging a core file.

opcodes: blackfin: fix decoding of 32bit addresses on 64bit systems
The Blackfin ISA is very exact with regards to address truncation when
under/over flowing its 32bit range. On a 32bit system, things work the
same and so addresses are decoded properly. On a 64bit system though,
the decoded addresses may include the bits that are supposed to have
been truncated. So force a 32bit truncation after the address has been
calculated.

opcodes: blackfin: fix decoding of many invalid insns
The Blackfin disassembler was originally based on the premise of parsing
valid opcodes all the time, so some of the opcode checking can be a bit
fuzzy. This is exemplified in decoding of parallel insns where many
times things are decoded as invalid when in reality, they may not be
used in parallel combinations. So add parallel checking to most insn
decoding routines so we see ILLEGAL and not just whatever insn happens
to be close to a valid mnemonic, as well as some additional sub-opcode
checks.
