Rui Ueyama 4bf771b4e6 readobj: Dump PE/COFF optional records. 
These records are mandatory for executables and are used by the loader.

Rui Ueyama 1a4f2a33fb [PECOFF] Remove COFF header from PE header for simplicity. 
COFF header is always present both in executable and in object file. PE header
is present only in executable. So the natural way to handle PE/COFF file is
treating COFF is mandatory header and PE is optional. Current data structre
does not allow it, because PE header includes COFF header. Removing COFF
header will simplify the code to handle PE/COFF files.

Rafael Espindola 6c1202c459 Handle relocations that don't point to symbols. 
In ELF (as in MachO), not all relocations point to symbols. Represent this
properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj
ELF's dumper to handle relocatios without symbols.

Rafael Espindola 167957fa09 Change getRelocationAdditionalInfo to be ELF only. 
It was only implemented for ELF where it collected the Addend, so this
patch also renames it to getRelocationAddend.

Andrew Kaylor 3a129c8592 This patch adds new functions to the SectionRef and ObjectFile interfaces to determine whether or not a section is meant to be read-only. These functions will be used by the MCJIT RuntimeDyld to give hints to the memory manager during the object loading process in a future patch.

Preston Gurd c68dda815e This patch improves the MCJIT runtime dynamic loader by adding new handling 
of zero-initialized sections, virtual sections and common symbols
and preventing the loading of sections which are not required for
execution such as debug information.

Benjamin Kramer ac241fe9f0 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.
