Second try of initial ARM/Thumb disassembler check-in. It consists of a tablgen backend (ARMDecoderEmitter) which emits the decoder functions for ARM and Thumb, and the disassembler core which invokes the decoder function and builds up the MCInst based on the decoded Opcode.

ADR was added with the wrong encoding for inst{24-21}, and the ARM decoder was fooled. Set the encoding bits to {0,?,?,0}, not 0. Plus delegate the disassembly of ADR to the more generic ADDri/SUBri instructions, and add a test case for that. llvm-svn: 128234

There were two issues fixed: 1. The ARM Darwin *r9 call instructions were pseudo-ized recently. Modify the ARMDisassemblerCore.cpp file to accomodate the change. 2. The disassembler was unnecessarily adding 8 to the sign-extended imm24: imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate) // Encoding A1 It has no business doing such. Removed the offending logic. Add test cases to arm-tests.txt. llvm-svn: 127707
