Add Thumb encodings for REV instructions. llvm-svn: 120277

@ RUN: llvm-mc -triple thumbv6-apple-darwin -show-encoding < %s | FileCheck %s
Add MC encodings for some Thumb instructions. Test for a few of them. The "bx lr" instruction cannot be tested just yet. It requires matching a "condition code", but adding one of those makes things go south quickly... llvm-svn: 119774

Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almost certainly be made more generic. But it does allow us to parse something like: ldr r3, [r2, r4] correctly in Thumb mode. llvm-svn: 120408

Fix encoding and add parsing support for the arm/thumb CPS instruction: - Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. llvm-svn: 125489

ARM asm parser wasn't able to parse a "mov" instruction while in Thumb mode (only the "mov.w" variant). Now, when parsing "mov" in thumb mode, default to the Thumb 1 versions/encodings. llvm-svn: 132233
