Owen Anderson 000721f058 The VMAs stored in the symbol table of a MachO file are absolute addresses, not offsets from the section.

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.

Chandler Carruth 9d7feab3e0 Rewrite the CMake build to use explicit dependencies between libraries, 
specified in the same file that the library itself is created. This is
more idiomatic for CMake builds, and also allows us to correctly specify
dependencies that are missed due to bugs in the GenLibDeps perl script,
or change from compiler to compiler. On Linux, this returns CMake to
a place where it can relably rebuild several targets of LLVM.

I have tried not to change the dependencies from the ones in the current
auto-generated file. The only places I've really diverged are in places
where I was seeing link failures, and added a dependency. The goal of
this patch is not to start changing the dependencies, merely to move
them into the correct location, and an explicit form that we can control
and change when necessary.

This also removes a serialization point in the build because we don't
have to scan all the libraries before we begin building various tools.
We no longer have a step of the build that regenerates a file inside the
source tree. A few other associated cleanups fall out of this.

This isn't really finished yet though. After talking to dgregor he urged
switching to a single CMake macro to construct libraries with both
sources and dependencies in the arguments. Migrating from the two macros
to that style will be a follow-up patch.

Also, llvm-config is still generated with GenLibDeps.pl, which means it
still has slightly buggy dependencies. The internal CMake
'llvm-config-like' macro uses the correct explicitly specified
dependencies however. A future patch will switch llvm-config generation
(when using CMake) to be based on these deps as well.

This may well break Windows. I'm getting a machine set up now to dig
into any failures there. If anyone can chime in with problems they see
or ideas of how to solve them for Windows, much appreciated.

Eric Christopher ee066fc4f3 Assorted bugfixes in object file handling: 
- Adds support for sniffing PE/COFF files on win32 (.exe and .dll)
   which are COFF files that have an MS-DOS compatibility stub on
   the front of them.

 - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF
   extension for long symbol names, wherein it was attempting to parse
   the leading '/' in an extended symbol name reference as part of the
   integer offset.

 - Fixes bugs in COFFObjectFile and ELFObjectFile wherein section
   and symbol iterators were being returned with uninitialized bytes;
   the type DataRefImpl is a union between 2 32-bit words (d.a and d.b)
   and a single intptr_t word (p). Only p was being initialized, so in
   32-bit builds the result would be iterators with random upper 32-bit
   words in their DataRefImpls. This caused random failures when
   seeking around in object files.
