cbe72fc959 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.

52823cc91c build: Attempt to rectify inconsistencies between CMake and LLVMBuild versions of explicit dependencies. 
- The hope is that we have a tool/test to verify these are accurate (and tight) soon.

fa3e5200b8 Add support for the notion of "hidden" relocations. On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves. 
I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden.

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.
