with two kinds, and some more specific predicates that clients can use.
The notion of 'computed or not' isn't specific enough for how properties
are accessed. We already have problems with ObjC properties that are
stored but usually accessed through getters and setters, and a bool here
isn't helping matters.

1. Implement parser and sema support for our subscript syntax proposal in
protocols. Now you have to use subscript(..) { get } or {get set} to
indicate what you want. I suspect that the syntax will evolve, but at
least we can express what we need now.
2. Change the representation of SubscriptDecls in protocols to make
(empty) funcdecls for the getter and setter. This guarantees that
every subscript has at least a getter.

Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.
No functionality change, but should speed up compile times!

This attribute states that all stored properties within the class must
provide initial values. This will allow us to move stored property
initialization into Objective-C's post-allocation initialization hook,
.cxx_construct.

General compiler support is missing for 'type' properties on classes, and lets don't
work either, but at least we have a nice diagnostic now.
also, rename static -> type in a few internal diagnostic names.

- improve error recovery when rejecting lets with getters/setters.
- mark the 'self' parameter of an implicitly generator init() method
as 'let' when it is for a class.

Switch some diagnostic text from 'static' over to 'type' to make
things easier, and fix up some parsing issues with selector-style
declarations found by doing this. NFC

This allows them to appear in argument lists of functions, enabling behavior
like this:
func test_arguments(a : Int, var b : Int, let c : Int) {
a = 1 // ok (for now).
b = 2 // ok.
c = 3 // expected-error {{cannot assign to the result of this expression}}
}

typealias MyInt: ForwardIndex = Int
There is no real reason to allow this; it's just a static_assert that Int
conforms to ForwardIndex, which would be better spelled some other way.
This only applies to concrete typealiases, i.e. those that simply alias an
underlying type. Associated types can still have both inheritance clauses
and a (default) underlying type.

Derive the appropriate ExtraData for a SILFunctionType from its thinness and calling convention. Consider @!thin @cc(witness_method) as having ExtraData::Metatype. This should eliminate all of the unspoken gentleperson's agreements that let thin and witness functions survive IRGen currently when we can turn on SIL witness tables.

- Switch @mutable to be a tri-state attribute that is invertable with @!mutable.
- Move the semantic form of 'mutable' to being a bit on FuncDecl instead of
something in DeclAttrs. The former is a binary bit, the later is a tristate
which differentiates between "not present", "present and set" "present and inverted".
- Diagnose some invalid uses of @mutable, e.g. on class methods.
- Make setters default to mutable, and allow them to be switched with @!mutable.

arguments. Until we have @inout methods on structs, we can't mark anything
that can be address-exposed. This temporarily regresses a few testcases,
but they will come back later.

The parser shouldn't be diagnosing such semantic constraints. While
I'm here, allow definitions on functions in protocols (they're ignored
for now).

var decls. I was originally intending to use this for argument lists, but I
don't think that's a great direction to go anymore.
In any case, it seems uncontroversial to enforce immutability on foreach
enumation patterns, so I did that (see testcase)

are not settable (like get-only ones). Set the 'isLet' bit in various
places, but not the particularly interesting or useful places yet.

Have ArchetypeBuilder key the archetypes it produces by the abstract {depth,index} position of generic parameters rather than by the identity of particular GenericTypeParamDecls. Tighten the signature of AbstractTypeParamDecl-taking methods to only take GenericTypeParamDecls; that's the only case that comes up anymore. Introduce 'addGenericParameter' and 'getArchetype' overloads that work with GenericTypeParamTypes and DependentMemberTypes in addition to those that work with GenericTypeParamDecls.
Move ArchetypeBuilder.cpp from 'Sema' to 'AST' to correspond to its header's location.
When we parse something like 'protocol P { protocol Q {} }', eagerly give the erroneous nested protocol Q an ErrorType to suppress type-checking of the declaration. Otherwise, the nested implicit 'Self' parameters, which are fixed depth 0 index 0 in the generic parameter space, will collide in the ArchetypeBuilder.
