before encoding.

MC/Mach-O/x86_64: Add a new hook for checking whether a particular section can
...
be diced into atoms, and adjust getAtom() to take this into account.
- This fixes relocations to symbols in fixed size literal sections, for
example.

MC: Add TargetAsmBackend::createObjectWriter.

- MCAssembler is now object-file independent, although we will surely need more work to fully support ELF/COFF.

MC/Darwin: Add a new target hook for whether the target uses "reliable" symbol differences, basically whether the assembler should attempt to understand atoms when using scattered symbols.
...
Also, avoid some virtual call overhead.
