Michael J. Spencer 289dcedea5 [ELF] Add support for IFUNC. 
This sadly doesn't have a test for the final
output because llvm-objdump can't dump relocations
that don't belong to a section :(

Michael J. Spencer 64afcb4c6b Move everything over to TargetInfo. 
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

Michael J. Spencer 8b3898af26 [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.

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.

Sid Manning 42064e5b60 * Add relocation reference support for Hexagon and PowerPC. 
- Hexagon has many relocation types, this patch covers just
      a subset, more will be added.

      environments.
  * Add some basic test cases
  * Update ldd-core to accept -endian flag
