This fixes a recent regression (r183338). Stripped elf files (like installed
crtn.o for example), are not required to have a symbol table. Handle that
correctly.

lld can now output a valid Windows executable with a text section that does nothing
but just returns immediately. It's not able to handle relocations, symbol tables,
data sections, etc, so it still can't do anything practical, though.

This is the parser for the ENTRY command. Note that because the parsing result
is currentlyd discarded, lld can parse but just ignore the command.

Users can override the default value of the dynamic linker to be set to the
one that appears in the command line. The path can even be empty!. 

Added a test for the option.

Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

This addresses comments raised by Sean/Rafael.

only if they are relative. This removes the FIXME when the
relocations are being emitted and checks if the relocation
is relative and only then populates the addend information.

I couldnt add a testcase for this as llvm-readobj lacks     
functionality of printing dynamic relocations.              

When the functionality is added, remove the commented lines
from elf/ifunc.test to test functionality.

This patch splits X86_64Target specific code so that 
the dynamic atoms and the Relocation handlers are in seperate 
files for easier maintenace. The files are sure to grow and this 
makes it easier to work with.

This makes the target handler a constructor argument because the constructor of
OutputELFWriter relies on it being initialized.

Moved llvm_unreachable out of switch blocks to avoid the "control reaches end of non-void function" warning.

to the list of undefined atoms. 

The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option. 

This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.
