8e956ff30c llvm-objdump: Dump COFF import table if -private-headers option is given. 
This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.

f2baef0d6e Retry submitting r186623: COFFDumper: Dump data directory entries. 
The original change was rolled back in r186627 because of test
failures on the big endian machine. I believe I fixed the issue
so re-submitting.

f7419da108 COFFDumper: Dump data directory entries. 
Summary:
Dump optional data directory entries in the PE/COFF header, so that
we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.
I don't know how the previous file was linked, but the previous file did
not have any data directory entries for some reason.

6f41305fd8 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.

56fa3ce519 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.

9541db893e Clarify getRelocationAddress x getRelocationOffset a bit. 
getRelocationAddress is for dynamic libraries and executables,
getRelocationOffset for relocatable objects.

Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a
test of ELF's. llvm-readobj -r now prints the same values as readelf -r.

b850da774b 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.

6e9bcca355 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.

is unknown, not that the symbol is undefined. (For that, use ST_Undefined).
