a894c8e344 llvm-objdump: factor code better, add comments.

0b8b771e9f Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO.
- It can take FunctionStarts from a binary to find entry points more accurately.
- Symbol offsets in executables are correct now.

98c5ddabca Don't attach annotations to MCInst's. Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

41ab14b725 Add MCInstrAnalysis class. This allows the targets to specify own versions of MCInstrDescs functions.
- Add overrides for ARM.
- Teach llvm-objdump to use this instead of plain MCInstrDesc.

853b0fd623 llvm-objdump: Ignore unreachable blocks when printing the CFG.

83a162ef85 llvm-objdump: Skip branches that leave the current function.
In "normal" code these only happen when disassembling data, so we
won't lose anything if we just drop them.

c3d48cee49 Unbreak the MSVC build. Since the "next" function already exists in the MSVC headers, we need the explicit llvm:: qualifier to prevent a conflict.

685a2501b2 Sketch out an CFG reconstruction mode for llvm-objdump.
- Not great yet, but it's a start.
- Requires an object file with a symbol table. (I really want to fix this, but it'll need a whole new algorithm)
- ELF and COFF won't work at the moment due to libObject shortcomings.

To try it out run
$ llvm-objdump -d --cfg foo.o

This will create a graphviz file for every symbol in the object file's text section containing a CFG.
