This meant we weren't producing sema diagnostics for the case, and it didn’t
get full syntactic/semantic highlighting or indentation.

Query the SourceLookupCache for the operator decls,
and use ModuleDecl::getOperatorDecls for both
frontend stats and to clean up some code
completion logic.
In addition, this commit switches getPrecedenceGroups
over to querying SourceLookupCache.
Add `AdditiveArithmetic` derived conformances for structs and classes, gated by
the `-enable-experimental-differentiable-programming` flag.
Structs and classes whose stored properties all conform to `Differentiable` can
derive `Differentiable`:
- `associatedtype TangentVector: Differentiable & AdditiveArithmetic`
- Member `TangentVector` structs are synthesized whose stored properties are
all `var` stored properties that conform to `Differentiable` and that are
not `@noDerivative`.
- `mutating func move(along: TangentVector)`
The `@noDerivative` attribute may be declared on stored properties to opt out of
inclusion in synthesized `TangentVector` structs.
Some stored properties cannot be used in `TangentVector` struct synthesis and
are implicitly marked as `@noDerivative`, with a warning:
- `let` stored properties.
- These cannot be updated by `mutating func move(along: TangentVector)`.
- Non-`Differentiable`-conforming stored properties.
`@noDerivative` also implies `@_semantics("autodiff.nonvarying")`, which is
relevant for differentiable activity analysis.
Add type-checking and SILGen tests.

- Show static var decls in non-qualified metatype lookup
- Show enum element decls in non-qualified metatype lookup
- Never show initializers in non-qualified lookup
- Perform instance lookups in lazy var initializer
- Perform non-qualified metatype lookup inside static func

in typechecked AST. This is needed to correctly get the type of the
parsed expression when the expression is a calling to a method in super
class returning 'Self'.

If a cross-import overlay shadows another module and has a name starting with
'_', don't present that overlay in places where module name completions are
offered and present symbols comining from that module as if they came from
the shadowed module instead.

- In member completions, when 'callAsFunction' decls are found, suggest
call patterns
- In call pattern completions, fallback to search 'callAsFunction' if
the base type is not a function type

Call arguments sometimes affect the inference for the generic parameters of the
type expression. When we want to show all initializers from all
extensions, we do not want to infer any generic arguments.

instead of the pre-typechecked type and the referenced decl in the AST
so that we can suggests all overloads even if it happen to be
typechecked to a method. For example
struct MyType {
func foo() {}
func foo(_ int: Int) {}
func foo(name: String, value: String) {}
}
func test(val: MyType) {
value.foo(#^COMPLETE^#)
}
In this case, the call is typechecked to 'MyType.foo(_:)', but we want
to suggest all overloads.

The SyntaxModel walker would end up visiting the attributes attached to a
PatternBindingDecl twice if it contained more than one VarDecl, hitting the
below assertion on the second visit because the tokens corresponding to the
attribute had already been consumed the first time around:
```
Assertion failed: (0 && "Attribute's TokenNodes already consumed?"), function
handleSpecialDeclAttribute
```
It would also hit the same assertion for attributes on an EnumCaseDecl, but even
when it only had a single child EnumElementDecl. This because when we visited
the EnumCaseDecl and pushed its structure node, we'd consume and emit any tokens
before it's start position. This meant that when we tried to process the
attributes attached to the child EnumElementDecl its tokens had already been
consumed, triggering the assertion.
In both cases the attributes syntactically attach to the parent
PatternBindingDecl or EnumCaseDecl, but in the AST they're accessed via their
child VarDecls or EnumElementDecls.

If a CC token is right after the '{' we still don't know it's an implicit
getter or a start of a accessor block. Previously, the parser used to
parse it as an accessor block, but it prevents fast-completion kicks in.
Instead handle it as a part of function body parsing so the
fast-completion works.

Lazy loading checked if the ClangDecl was hidden, but loading all
members did not. Let's make loadAllMembers() behave like the lazy
path, and fix some of the mock SDKs in the test suite.
Add a platform kind and availability attributes for macCatalyst. macCatalyst
uses iOS version numbers and inherits availability from iOS attributes unless
a macCatalyst attribute is explicitly provided.
