Rafael Espindola a0af48fc93 Fix handling of files without a symbol table.
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.

Rui Ueyama a6b71cabb3 [LayoutPass] Add a method to check the followon graph structure.
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.

Rui Ueyama 8d6151fd29 [PECOFF][Writer] Implement the writer that can emit text section.
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.

Rui Ueyama 143672c7e5 [lld][ELF] Add parser for linker script ENTRY command
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.

cannot link or output PE/COFF files yet.

Shankar Easwaran d8da989e78 [lld][LayoutPass] An earlier commit moved the functionality so that Atoms would
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.

Shankar Easwaran 9af77a2cab [lld][ELF][All Archs] Addend is used by dynamic relocations
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.

Shankar Easwaran f9a7933d90 [lld][ELF][X86_64] Reorganize X86_64 Target specific code
This patch splits X86_64Target specific code so that

files for easier maintenace. The files are sure to grow and this 
makes it easier to work with.
