Jim Grosbach ec9ba98299 Thumb2 prefer encoding T3 to T4 for ADD/SUB immediate instructions.

Jim Grosbach 6efa7b9852 Thumb2 assembly parsing for mul.w in IT block fix. 
When the 3rd operand is not a low-register, and the first two operands are
the same low register, the parser was incorrectly trying to use the 16-bit
instruction encoding.

Jim Grosbach b009a872d7 Add Thumb2 alias for "mov Rd, #imm" to "mvn Rd, #~imm". 
When '~imm' is encodable as a t2_so_imm but plain 'imm' is not. For example,
  mov r2, #-3
becomes
  mvn r2, #2

Jim Grosbach 7a49575d7f Thumb2 ADD/SUB instructions encoding selection outside IT block. 
Outside an IT block, "add r3, #2" should select a 32-bit wide encoding
rather than generating an error indicating the 16-bit encoding is only
legal in an IT block (outside, the 'S' suffic is required for the 16-bit
encoding).

Jim Grosbach 61fdba048f Thumb2 ldr pc-relative encoding fixes. 
We were parsing label references to the i12 encoding, which isn't right.
They need to go to the pci variant instead.
