7be76590e6 Expand relocation type field to 64 bits. MachO scattered relocations require 33 bits of type info.

1d19f97ea5 Object: Add some types to SymbolRef::Type.
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.

9bfcf77638 lib/Object/ELFObjectFile.cpp: Fix undefined behavior for MC/ELF/many-section.s not to fail (on msvc).
DenseMap::lookup(k) would return "default constructor value" when k was not met. It would be useless when value type were POD.

7adc4370e0 Add support for .symtab_shnidx. Unfortunately, doing this required breaking a
layer of abstraction around SymbolRef where you can read its private
SymbolPimpl member.

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.

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.

f6f3e81c07 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.

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.
