73e4d372d0 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.

82df2a3e37 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.

e54c4beb5a 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.

52607b3842 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.

9df16051f4 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.

6c9a683f71 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.
