8b89224c6e David Brownell <david-b@pacbell.net>: 
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.

b71e3aff6d David Brownell <david-b@pacbell.net>: 
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.

309870e414 David Brownell <david-b@pacbell.net>: 
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.

2) Switch back to correct development branch during final release step.
3) Add do_svn_switch helper to ensure package variables are reloaded.
