Fixed ObjectFile functions:
- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
- fixed MachOObjectFile::getSymbolSize()
- fixed MachOObjectFile::getSymbolSection()
- fixed MachOObjectFile::getSymbolOffset() for symbols without section data.

Some of these can be true at the same time and there are a lot to add,
so this should be turned into a bitfield. Some of the other accessors
should probably be folded into this.

Reapply r141605 with fixes for appropriate handling of reserved section numbers
in st_shndx fields.

llvm-svn: 141639

Add support for .symtab_shnidx. Unfortunately, doing this required breaking a
layer of abstraction around SymbolRef where you can read its private
SymbolPimpl member.

Revert r141605 as it broke tests for llvm-nm.

llvm-svn: 141614

Add support for reading many-section ELF files.
If you want to tackle adding the testcase, let me know. It's a 4.2MB ELF file
and I'll be happy to mail it to you.

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.
