sim: arm: add support for MOVW and MOVT instructions
From: Jayant R. Sonar <Jayant.Sonar@kpitcummins.com>
This patch adds simulator support for handling the armv7 instructions
'movw (immediate)' and 'movt'.
Compiler frequently use these instructions to load the 32bit addresses of
global variables, string pointers etc. into the general registers.
In absence of support of these instructions:
1. GDB run simulator fails to print even simple "hello world" string
on console.
2. Loading of global variable addresses into the registers fail causing
arithmetic operation failures.
Patch has been regression tested for arm-none-eabi (-march=armv7-a).

ppc-aix core file relocation.
The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat

on the target stack at all when debugging core files, thus bypassing

PR remote/15455 - QTro remote packet broken
In the function remote_trace_set_readonly_regions in gdb/remote.c, the
local variable 'offset' does not account for "QTro" at the start of
the packet with the result that if there are any read-only regions,
the packet is sent -- but without the "QTro" -- causing the remote
stub to report that the packet is unsupported:
We don't see the problem when testing with GDBserver, as that supports
qXfer:trace-frame-info:read, meaning GDBserver never needs to read
from the read-only sections directly itself. This commit adds a test
that explicitly disables qXfer:trace-frame-info:read.

move sparc-sol-thread.c back into sol-thread.c.
The routines in sparc-sol-thread used to be SPARC-specific (and
documented as such in the ptrace man page), and therefore hosting them
in a sparc-specific file made sense. However, newer versions of
Solaris now use those callbacks (Solaris 10 Update 10, apparently),
and thus the note about these callbacks being specific to SPARC
was removed.
So this patch deletes sparc-sol-thread.c and moves the code back
inside sol-thread.c.

Improve output of "maintenance info sol-threads" command.
This patch does the following:
- Puts the startfunc and "Sleep func" info on the same line;
- Renames "Sleep func" into "sleepfunc" to be consistent with
"startfunc"
- Avoids the use of a '-' as a separate before the "sleepfunc"
output, because the '-' looks odd and out of place when the
"startfunc" field is not printed (ti.ti_startfunc is nul).
- Use a '=' instead of ':' and avoids the space between
the name of the value and its value, mostly to help group
the value with its name.
For the record, this is how the new outout now looks like:
(gdb) maintenance info sol-threads

It should be safe to perform this comparison on all architectures.
