1ac382f0c5 [ELF] Emit the file header and program headers at the beginning of the first segment.

6b079f5e2f Removes files for separate ReaderYAML.cpp and WriterYAML.cpp 
and adds a new file ReaderWriterYAML.cpp that uses YAML I/O.

Lots of tweaks to test suite for slightly different YAML encoding.

9ff4be240a Add the core architecture for the lld driver. 
This includes selecting which driver to emulate, option parsing, invocation
building, and running the link. This currently only supports a very basic
subset of ld for x86_64-linux.

lld -flavor ld obj.o -o obj

or symlink lld as (ld , link, ld64, core) to get the desired behavior without
-flavor.

cl is not attempting to complete a templated class when used in this
