Owen Anderson d9243c4689 Rewrite most of MachODump to work through the generic libObject interfaces rather than accessing the MachO internals directly.

Michael J. Spencer ee84f64f0b llvm-objdump: Fix dumping of multiple symbols with the same address. 
This happens in COFF because there is a symbol for the beginning of each
section.

Nick Lewycky fcf8462583 Add support for dumping section headers to llvm-objdump. This uses the same 
flags as binutils objdump but the output is different, not just in format but
also showing different sections. Compare its results against readelf, not
objdump.

Benjamin Kramer 8a529dc10a llvm-objdump: Detach symbol listing from section enumeration for mach-o. 
This reduces memory usage as we don't add the same symbol multiple times anymore.

Benjamin Kramer 43a772eda1 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.

Owen Anderson a0c3b97221 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.

Benjamin Kramer 75d1cf3391 Object: make the following changes into SymbolRef 
- Add enum SymbolType and function getSymbolType()
- Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions.
- Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address.
- Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

Evan Cheng 2bb4035707 Move TargetRegistry and TargetSelect from Target to Support where they belong. 
These are strictly utilities for registering targets and components.

Evan Cheng 4d6c9d711d Some refactoring so TargetRegistry.h no longer has to include any files 
from MC.

Benjamin Kramer c22d50e5c3 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.

Benjamin Kramer cb2d7bee35 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.

Chandler Carruth 2d71c421f9 Move the registered target printing in version strings completely out of 
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.

The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

Francois Pichet 7f023ae4bb Unbreak the MSVC build. Since the "next" function already exists in the MSVC headers, we need the explicit llvm:: qualifier to prevent a conflict.

Benjamin Kramer 87ee76ca73 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.
