fix several thumb2 decode bugs
- 32-bit store encodings with the imm12 bit (bit 23) set were decoded as
the register-offset form when imm12 < 64, or as strbt/strht/strt when
imm12 was 0xExx. bit 23 set always means the imm12 form.
- movw/movt packed imm4 at bit 16 instead of bit 12, producing 20-bit
immediates (e.g. 0xf0005 instead of 0xf005)
- mvn (immediate) was decoded as mov, dropping the bitwise not
- ror (immediate) was decoded as asr
all cases verified against binutils objdump
