is that it is a fixed void* value that points to an memory address that remains
valid throughout the remainder of the lifetime of the SymbolManager.

Partial fix for <rdar://problem/6645157> [clang on Xcode; regression]: error: instance variable 'someField' is private.

A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev.

This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline.

Finish up some fixes related to <rdar://problem/6497631> Message lookup is sometimes different than gcc's.

- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

codegen, until such time as codegen is complete enough to turn on with

 - Add Options.def file, collects option information.

 - Actual option instantiation is handled lazily by OptTable to allow
   the driver to not need to instantiate all options.

 - cast<> support for Option, other minor tweaks.
