Replace the 'final' keyword with 'LLVM_FINAL' as GCC 4.6 doesn't support
...
the keyword.
If anyone cares deeply about the final optimizations with GCC, we might
want to add a version test to the LLVM definition, but I'm perfectly
happy with this just only firing under Clang and modern MSVC builds.

[ELF] Never allocate content to weak symbols as they may be merged away.

This is done by creating a new non-weak anonymous symbol and creating
an atom with content for that symbol. This is added after the weak symbol
so that they have the same address.

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.
