Rui Ueyama a3eff3afd9 Make -core/-flavor options have higher priority than linker name 
Also allows -core/flavor to appear at any position in the command line.

Rui Ueyama a726ef12a4 Make getFlavor function. 
The dangling "else" at the end of #if looked a bit error-prone.
Make it a separate function. No functionality change.

Nick Kledzik 50bda292c8 If lld is renamed (or symlinked) to "ld" automatically pick the right flavor. 
The existing system linkers on Darwin and Linux are called "ld".  We'd like to
eventually drop in lld as "ld" and have it just work.  But lld is a universal
linker that requires the first option to be -flavor to know which command line
mode to emulate (gnu or darwin).

This change tests if argv[0] is "ld" and if so, if the tool was built on MacOSX
then assume the darwin flavor otherwise the gnu flavor.  There are two test
cases which copy lld to "ld" and then run it. One for darwin and one for linux.

Rui Ueyama 83ba74fa3f [PECOFF] Rename link.exe -> lld-link.exe. 
Creating the file "link.exe" made some confusion, so it's better to
name it lld-link.exe, as we did for CL (clang-cl.exe).

Rui Ueyama 8db1eddc07 Make Driver::link and LinkingContext::validate return true on success. 
This patch inverts the return value of these functions, so that they return
"true" on success and "false" on failure. The meaning of boolean return value
was mixed in LLD; for example, InputGraph::validate() returns true on success.
With this patch they'll become consistent.

Rui Ueyama 9e56839a83 [lld][PECOFF] Add WinLinkDriver and PECOFFTargetInfo. 
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.

Nick Kledzik c314b46e71 This is my Driver refactoring patch. 
The major changes are:
1) LinkerOptions has been merged into TargetInfo
2) LinkerInvocation has been merged into Driver
3) Drivers no longer convert arguments into an intermediate (core) argument 
   list, but instead create a TargetInfo object and call setter methods on 
   it. This is only how in-process linking would work. That is, you can 
   programmatically set up a TargetInfo object which controls the linking.
4) Lots of tweaks to test suite to work with driver changes
5) Add the DarwinDriver
6) I heavily doxygen commented TargetInfo.h

Things to do after this patch is committed:
a) Consider renaming TargetInfo, given its new roll. 
b) Consider pulling the list of input files out of TargetInfo. This will 
   enable in-process clients to create one TargetInfo the re-use it with 
   different input file lists.
c) Work out a way for Drivers to format the warnings and error done in 
   core linking.
