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.

Add support for relocations to ObjectFile.

Patch by Danil Malyshev!

llvm-svn: 139314

ObjectFile: Add a method to check whether a section contains a symbol.

- No ELF or COFF implementation yet, I don't have a way to test that.
Should be straightforward to add though.

Make Binary the parent of ObjectFile and update children to new interface.

llvm-svn: 132911

Remove dead variable pointed out by GCC 4.6 warnings, and reflow this a little
to scope a variable more tightly per llvm coding style. No functional change.

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.

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.
