When we walk a ClassDecl, generate its vtable, first pulling in decls from its ancestor classes, then overlaying overridden or new decls as we discover them.

These will provide a SIL-level representation of class_method dispatch, mapping from dynamically-dispatched SILDeclRefs to SILFunctions so that devirtualization passes will be able to promote a class_method for a statically-known type to a function_ref without going all the way back to the AST.

These are the terms sent out in the proposal last week and described in
StoredAndComputedVariables.rst.
variable
anything declared with 'var'
member variable
a variable inside a nominal type (may be an instance variable or not)
property
another term for "member variable"
computed variable
a variable with a custom getter or setter
stored variable
a variable with backing storage; any non-computed variable
These terms pre-exist in SIL and IRGen, so I only attempted to solidify
their definitions. Other than the use of "field" for "tuple element",
none of these should be exposed to users.
field
a tuple element, or
the underlying storage for a stored variable in a struct or class
physical
describes an entity whose value can be accessed directly
logical
describes an entity whose value must be accessed through some accessor

Doug pointed out that 'isObjC' incorrectly excludes C functions, for which we'll also need to be able to independently reference Swift and foreign entries.

We want the argument generator functions to be treated as transparent iff the "parent" function is transparent. There is no need to special case it in isTransparent because the SILDeclRef contains the :parent" Decl, and the first check will just work for us automatically.
Do make sure that the isTransparent is consulted when the apply instruction is created.

Thunks above the natural uncurry level of a function should always be emitted with standalone function CC instead of method or foreign CC. Partially addresses <rdar://problem/14687373>, but we still don't emit thunks for struct instance methods.
Swift SVN r8043
We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!
Swift SVN r6783
"SILConstant" doesn't really describe its role in SIL anymore, which is to provide a reference to a Swift declaration in a SIL instruction, such as a method or nominal type field.
