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.

Found that having a method to check the strucutre of the followon graph makes
it easy to debug file readers. The method checks if there's no wrong edge in
followOnNexts and followOnRoots. It is called only when debuggging is enabled
for LayoutPass.

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.

The code to actually consume these flags will be added soon.

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.

DEBUG_TYPE is already defined at the beginning of this file. We don't
want to have two different debug flags for a single pass.

be laid out by their ordinal overrides first, there was a bug that two atoms may 
get the same override index due to which atoms were not ordered properly. This
commit fixes the problem.

Now the atoms are ordered by 

- Section Position hints
- Atom override (Using layout-after/layout-before/in-group)
- Content Permissions
- Content Type
- File Ordinal

This also fixes the problem of running c++ static executables that 
was broken by an earlier patch.

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.

Summary:
Split buildFollowOnTable to small functions to improve
code readability and remove code duplication. No change
in functionality.
