[ia64-linux] Allow libunwind to fetch register 0

On ia64-linux, GDB sometimes prints the following error when trying
to switch to a different task:

    (gdb) task 3
    Register 0 is not available

This is a random failure that sometimes happens, sometimes does not.
The error comes from the fact that the libunwind library is requesting
the value of register 0 (zero): This eventually leads us to
ia64-linux-nat.c:ia64_linux_fetch_register.

This function relies on ia64_cannot_fetch_register to determine
whether or not we have access to the register's value.  The ptrace
interface does not provide the r0 value, and so we end up telling
the regcache that this register's value is not available.  And yet,
for r0, we do not need to ask ptrace for its value, since it is
always zero.

So, the fix was to add a special rule for supplying a nul value
when regnum == IA64_GR0_REGNUM.

gdb/ChangeLog:

        * ia64-linux-nat.c (ia64_linux_fetch_register): Add special
        handling for r0.

Similar to logic in the cris exp, attempt a simple compile and if it fails

SEGV during AX eval of OP_DOUBLE (unsupported)

To reproduce the problem, simply try the following with any program:

    (gdb) maintenance agent-eval 1.0
    Critical error handler: process [...] terminated due to access violation

(this is on Windows; on GNU/Linux, the libc copes better)

The problem is quite simple: gen_expr is given an expression that
contains an unrecognized operator (OP_DOUBLE in this case). When that
happens, it tries to report an error with a string image of the operator
in the error message.  Conversion of the opcode into a string is done
using op_string which, despite its name, probably is not what the author
was looking for.  This function returns NULL for a lot of the opcodes,
thus triggering the crash.

There is a function that corresponds to what we are looking for:
expprint.c:op_name. It was static, though, so I made it non-static,
and used it from ax-gdb.c:gen_expr.

gdb/ChangeLog:

        * expression.h (op_name): Add declaration.
        * expprint.c (op_name): Remove declaration.  Make non-static.
        * ax-gdb.c (gen_expr): Use op_name instead of op_string.

sim: bfin: add exhaustive parallel-insn tests

sim: bfin: unify se_all*opcodes tests

The current se_all*opcodes tests are very similar in how they work.
In preparation for adding more tests along these lines, unify the
common bits into a framework that others can include and build off
of easily.

sim: bfin: add tests for new shift behavior

sim: bfin: fix corner case Logical shift issues

From: Robin Getz <robin.getz@analog.com>

Overflow with shift operations happens independently of saturation, but
we have the logic merged.  Extend the lshift function so that callers
can tell it when to handle each independently, and then do so when it's
needed.

sim: nrun: decode signal when crashing

This isn't entirely correct in that it assumes the signal numbering of
the target and host match, but seeing as we already make that assumption
in a few places, this patch doesn't make the situation any worse.

To make it easier to support ebiu banks at other addresses, move the base to
a runtime parameter rather than structure.  Future work will make this more
dynamic, but I'm waiting for more details first.
