It's still not as simple as it should be because of the many duplicated
lines, but it's at least better than before.

LLD still accepts both Unix and Windows style options when it's run as
link.exe. This patch does not change functionality.

llvm-svn: 187086

The /include command line option is equivalent to Unix --undefined
option, which forces the linker to resolve the given symbol name
as if it's an unresolved symbol in one of its input files. This feature
is used to link an additional object file or a shared library that no
input files refer to.

The logic to search a library from the library paths will be implemented
in a different patch.

Add support for -all_load. Enhance DarwinLdDriverTest unit test test cases to test all options parsed so far

This reverts commit 185657. It will be used by unit tests.

This renames variable name to reflect initial undefined symbols that are
defined by the linker -u option.

This doesnot change any functionality in lld, and updates code to reflect
Nick's comment.

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.
