Michael J. Spencer 57752dc56e Factor File::addAtom out to MutableFile::addAtom.

llvm-svn: 171992
 2013-01-09 20:10:30 +00:00
Nick Kledzik 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.

Michael J. Spencer 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.

This is required for the loader to correctly set AT_PHDR.

With this lld can correctly link against dietlibc and get to main.

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