The following instructions were enhanced with type dependent operands:
- convert_function
- pointer_to_thin_function
- upcast_inst
- thin_to_thick_function

I put in a simple fixup pass (MarkUninitializedFixup) for staging purposes. I
don't expect it to be in tree long. I just did not feel comfortable fixing up in
1 commit all of the passes up to DI.

A computed component needs:
- A stable identifier for equality checking. This can be either a static function reference for concrete property implementations, or a reference into a vtable or witness table for a dynamically dispatched property. This should correspond to a public ABI interface for public things.
- Getter and setter (TODO: and materializeForSet) references. These might be thunks to reach the necessary abstraction level for the keypath implementation, so they can't be used as stable identifiers directly.
- Separate out a uniquable KeyPathPattern that describes the context-free shape of the key path, with generic parameters and (eventually) subscript index slots factored out.
- Add component kinds for gettable and settable properties.
LLVM r299341 removed the llvm::integerPart typedef and replaced it
with llvm::APInt::WordType. The integerPartWidth constant was replaced
by llvm::APInt::APINT_BITS_PER_WORD.
This commit does a few things:
1. It uses SwitchEnumBuilder so we are not re-inventing any wheels.
2. Instead of hacking around not putting in a destroy for .None on the fail
pass, just *do the right thing* and recognize that we have a binary case enum
and in such a case, just emit code for the other case rather than use a default
case (meaning no cleanup on .none).

A lot of files transitively include Expr.h, because it was
included from SILInstruction.h, SILLocation.h and SILDeclRef.h.
However in reality most of these files don't do anything
with Exprs, especially not anything in IRGen or the SILOptimizer.
Now we're down to 171 files in the frontend which depend on
Expr.h, which is still a lot but much better than before.
This adds the underpinning for optimizing storage projections. When subobjects are composed in aggregate they no longer require individual copies.
Optimize copy->store sequences.
Added support for enums and existentials.
Added a mini design doc file comment.
Added -optimize-opaque-address-lowering unit tests.
This is the lifetime ending variant of fix_lifetime. It is a lie to the
ownership verifier that a value is being consumed along a path. Its intention is
to be used to allow for the static verification of ownership in deallocating
deinits which for compatibility with objective-c have weird ownership behavior.
