cc3d2dca60 Better tie together ContentType and Permissions.
Since most content types (e.g. typeCode) have a 
preferred Permission, add a function to do that mapping.
Then hook up to YAML Reader and Writer such that
the 'permissions:' key does not need to be specified unless
overriding what the content type prefers.

6047163a24 [lld] Add support for -mllvm.
There is no way to test this at the moment because the options are not
processed until the link starts, and we can't pass an empty file.

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