Benjamin Kramer 453173f09a Remove static ctor.

Eli Bendersky c7d23ddbbb Expose the ELFObjectFile class directly in the Object/ELF.h header, similarly
to what's done for MachO and COFF. This allows advanced uses of the class to
be implemented outside the Object library. In particular, the DyldELFObject
subclass is now moved into its logical home - ExecutionEngine/RuntimeDyld.

This patch was reviewed by Michael Spencer.

Dylan Noblesmith 1d966ae18e Object: avoid undefined behavior when bounds-checking
Don't form an out of bounds pointer just to test if it
would be out of bounds.

Also perform the same bounds checking for all the previous
mapped structures.

Eli Bendersky c3c80f0986 Basic runtime dynamic loading capabilities added to ELFObjectFile, implemented
in a subclass named DyldELFObject. This class supports rebasing the object file
it represents by re-mapping section addresses to the actual memory addresses
the object was placed in. This is required for MC-JIT implementation on ELF with
debugging support.

Patch reviewed on llvm-commits.

Developed together with Ashok Thirumurthi and Andrew Kaylor.

Danil Malyshev 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.

Owen Anderson 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.

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.
