Update ARM disassembler.

Fixes disassembly of Thumb data processing shifted-register instructions:
- Fix the opcode selection criteria: Rn/Rd==0xF (only Rn was tested).
- Print shift operand: type + immediate (for instance "lsl #3").

These instructions can be seen with oatdump when disassembling an oat file
generated by the Portable compiler.

Note: we do not use canonical form of shifted-mov here. We could improve this
by printing "lsl r1, r1, #3" rather than "mov r1, r1, lsl #3" to the output.
