The outer nullability is transferred from the declaration to the implementation so including them is redundant.
The inner ones are not transferred so they are kept to match the exact types. When we transfer the inner ones as well
adding them in the implementation will become redundant and we should strip those as well.

Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).
Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.
Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.

completion item. For example, if the code completion itself represents
a declaration in a namespace (say, std::vector), then this API
retrieves the cursor kind and name of the namespace (std). Implements

that was ignored in a few places (most notably, code
completion). Introduce Selector::getNameForSlot() for the common case
where we only care about the name. Audit all uses of
getIdentifierInfoForSlot(), switching many over to getNameForSlot(),
fixing a few crashers.
Fixed <rdar://problem/8939352>, a code-completion crasher.

type matches have a bigger impact. The impetus for this change was
that, when initializing an enumeration value, we want enumerators of
that enumeration type to have a higher priority than, e.g., unrelated
local variables.

declaring methods and when sending messages to them, by bringing all
of the selector into TypedCheck chunks in the completion result. This
way, we can improve the sorting of these results to account for the
full selector name rather than just the first chunk.

clang_codeCompleteAt(). This uncovered a few issues with the latter:
- ASTUnit wasn't saving/restoring diagnostic state appropriately between
reparses and code completions.
- "Overload" completions weren't being passed through to the client

at the statement level or in Objective-C message receivers. Therefore,
just give types and declarations the same basic priority, and adjust
from there.

present, prefer values to types, since it's more common to compute
with values than it is to declare new entities or perform type
casts. So, tweak the ranking of types vs. other declarations and
constants accordingly.

selector of an Objective-C method declaration, e.g., given
- (int)first:(int)x second:(int)y;
this code completion point triggers at the location of "second". It
will provide completions that fill out the method declaration for any
known method, anywhere in the translation unit.

definitions, e.g., after
-
or
- (id)
we'll find all of the "likely" instance methods that one would want to
declare or define at this point. In the latter case, we only produce
results whose return types match "id".
