Rui Ueyama 15ba1e20db Readobj: If NumbersOfSections is 0xffff, it's an COFF import library. 
0xffff does not mean that there are 65535 sections in a COFF file but
indicates that it's a COFF import library. This patch fixes SEGV error
when an import library file is passed to llvm-readobj.

Rafael Espindola e62ab11f09 Avoid some getSymbolNMTypeChar uses in COFFObjectFile.cpp itself. 
This is a fixed version of 193928 which keeps these uses in sync.

Rui Ueyama bc654b18bc Object/COFF: Rename getXXX{Begin,End} -> xxx_{begin,end}. 
It is mentioned in the LLVM coding standard that _begin() and _end() suffixes
should be used.

Rui Ueyama 5b1adbaad9 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.

Rui Ueyama ed64342b67 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.

Rui Ueyama a20b9f52d4 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.

Rafael Espindola 806f006490 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 0d15f7313f 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.

Rafael Espindola 1e48387962 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.

Andrew Kaylor 3f31fa05d5 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.
