Make the Thumb2 disassembler handle a bunch of 32-bit instructions:
A5.3.4 Branches and miscellaneous control
Note that this shifts some responsabililty out of helper functions,
making the code and layout simpler for 32-bit decoders: they only
need to know how to format the instruction and its parameters.
Also, technical note: with this patch, Thumb1 decoders could now
call the Thumb2 decoder if they wanted to get nicer treatment of
the exiting 32-bit B/BLX instructions.

Change layout of Thumb disassembly to work better with Thumb2:
- Move opcode to the left, allowing space for four hex bytes:
* after address, two spaces not one tab (taking 6 spaces)
* after 2-byte opcode, four spaces before tab
- Also, after opcode mnemonic use a tab not a space, to make
operands line up
Sample output (after some patches decoding a few 32-bit instructions):
0x00003e5a 0xf4423200 ORR r2, r2, #131072 ; 0x20000
0x00003e5e 0x601a STR r2, [r3, #0x0]
0x00003e60 0x2800 CMP r0, #0x00
0x00003e62 0xd1f3 BNE 0x00003e4c
0x00003e64 0xf008fa38 BL 0x0000c2d8
The affected lines of code now wrap at sane margins too.

Initial support for disassembling Thumb2 code. This works only for
Cortex-M3 cores so far. Eventually other cores will also need Thumb2
support ... but they don't yet support any kind of disassembly.
- Update the 16-bit Thumb decoder:
* Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added
by ARMv6. (It already seems to treat CPY as MOV.)
* Understand CB, CBNZ, WFI, IT, and other opcodes added by
in Thumb2.
- A new Thumb2 instruction decode routine is provided.
* This has a different signature: pass the target, not the
instruction, so it can fetch a second halfword when needed.
The instruction size is likewise returned to the caller.
* 32-bit instructions are recognized but not yet decoded.
- Start using the current "UAL" syntax in some cases. "SWI" is
renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM".
- Define a new "cortex_m3 disassemble addr count" command to give
access to this disassembly.
Sanity checked against "objdump -d" output; a bunch of the new
instructions checked out fine.

This patch correctly identifies a running target.
Patch made a tad more palatable by David Brownell <david-b@pacbell.net>

MOE(method of entry) - interpret this as dbgrq. "reset run" + "halt" + "step" now works.

Remove some bogus warnings during server startup for ARM926ejs
targets that were already halted for debug ... e.g. started up
a freshly built instance.
