Thanks very much for the comments. I've made the following changes:

- Changed the name of the files from SectionPatcher to AArch64ErrataFix. The technique for fixing errata isn't unique to AArch64, it has been applied to Arm before in other linkers, but I guess we can rename the file later if it becomes more generic.
- Removed the A64 struct.
- Got rid of GetInstr and simplified a bit.
- Created a function to remove some of the indentation.

Unfortunately mapping symbols aren't guaranteed to be ordered. It was thought too target specific to mandate in the ABI.
