Rebased after changes to https://reviews.llvm.org/D36749.

- We no longer initialize the mapping symbols in the constructor as we may be constructed but not used.
- If a patch is inserted we must update addresses again for thunks.

Still todo:

- The implementation assumes that no OutputSection is > 128 Mb. I've encountered at least one real world program (gitit) that has a 180 Mb .text section, so I'll need to fix that particular fixme.
