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.

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.

- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
