Subscripts are just another kind of property. Refactor some logic from ApplyExpr codegen to visit index arguments consistently with apply arguments. Also move the logic for determining SIL constant types onto SILModule because it's too hairy to calculate on the fly.

Generalize a bunch of code that assumed address-of-value-type for the "this" side of properties to accept reftypes as well. Use RefElementAddrInst to extract physical elements of reference types. Fix an off-by-one in the writeback logic in emitStoreToLValue so that writeback chains properly terminate at the deepest value type component below a reference type component.

- Steal some bits from SILConstant::id to reference getter and setter definitions, and normalize SILConstant references to property FuncDecls to be SILConstant references to the ValueDecl getter/setter instead.
- In normal expression context, handle getting properties by calling the getter and materializing the return value. Setting lvalues is not implemented yet; that will require borrowing the LValue and GenLValue machinery from irgen to construct logical lvalue paths in assignment and byref contexts.

Instead of considering `constant_ref @var` to give the address of `var` directly, consider it to be a `() -> [byref] T` function that returns the address, presumably after running the initializer for the global if necessary. Generate a DeclRef to a global var as a constant_ref to get the function followed by an apply to get the address. Actually generating the global accessor is still to be implemented.

We need something more general than ValueDecl to be able to talk about anonymous functions, curried entry points, etc. as SIL constants. SILConstant is a (ValueDecl | CapturingExpr) union with an additional index for discriminating multiple instances or entry points derived from the same AST entity. Update ConstantInst and SILModule's function table to be keyed by SILConstant rather than ValueDecl.

If the TranslationUnit being silgenned is a Main or Repl unit, generate globals like locals. Generating toplevel functions as closures still needs to be done.
Swift SVN r3340
Create a SILModule type, and lift ownership of TU-global things like the bump allocator and type list uniquing from Function to SILModule. Move the ad-hoc SIL dumping logic out of main() into SILModule and into a new SILGenModule class.
