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.
