Correct format:
```
//===--- Name of file - Description ----------------------------*- Lang -*-===//
```
Notes:
* Comment line should be exactly 80 chars.
* Padding: Pad with dashes after "Description" to reach 80 chars.
* "Name of file", "Description" and "Lang" are all optional.
* In case of missing "Lang": drop the "-*-" markers.
* In case of missing space: drop one, two or three dashes before "Name of file".
Now we can handle simple cases like
1 + 1 == 2 <here>
and correctly suggest both + on the 2 and || on the boolean. When the
LHS doesn't type-check we fallback to using only the operand immediately
to the left.

When users invoke code completion at an argument position, we suggest argument names,
if required however not specified, or a list of argument values. These values are annotated
with their type relation to the expected argument types, so that
Xcode can prioritize those values that apply over those that do not.

When users complete the right-hand side of an assignment expression, we only
show the results whose types are convertible to those of the left-hand side.

Before this commit, for unresolved members, code completion suggests all visible enum elements
and option set types. To refine the results, this commit uses constraint solver to infer
the type of unresolved members by analyzing parental expressions. If the solver has solutions,
we complete the unresolved member, otherwise abort.

This commit completes an unresolved member with all visible enum elements.
We need future work to reduce the list to those that are guaranteed to be
resolved under the current context.

When a user invoke code completion after import keywords, the names of
visible top level clang modules were recommended for finishing the import decl.

It's not okay to filter to only ErrorType results, since we may be
trying to chain to an error type result foo.bar.getError(). And the
existing logic had no way to handle results from other modules, so we
were missing key results like 'NSError'.
Eventually we'll want to bring back something like this that handles all
modules, but as a way to bump the priority of ErrorType results rather
than to filter out everything else.

This came out of today's language review meeting.
The intent is to match #available with the attribute
that describes availability.
This is a divergence from Objective-C.

When the code completion token appears after throw keyword,
a set of visible decls and instances conforming _ErrorType are
recommended as completion.

This patch also introduces some SILGen infrastructure for
dividing the function into "ordinary" and "postmatter"
sections, with error-handling-like stuff going into the
final section. Currently, this is largely undermined by
SILBuilder, but I'm going to fix that in a follow-up.

When a developer auto-completes an override function,
we collect the keywords that have already been specified
by the developer, so that the code completion strings do
not duplicate them.

In order for Xcode to use these completions, we complete "?.member" when the
user has typed "anOptional.", but we also say that in order to apply this
result, N bytes to the left of the cursor should be erased first.

class A {
init(a: Int) {}
}
A(#^HERE^#
In its current state, this is a hack that I am not proud of. There is
potential here to provide such completions for all function calls:
class A {
func foo(a: Int) {}
func foo(a: Double) {}
}
A().foo(#^HERE^#
but this requires code completion doing its own name lookup, since the type
checker will give us an error type due to ambiguity of overloaded functions.
Type checker also sometimes gives up in cases like these:
struct A {
func foo() {}
}
A().foo
which is understandable, since we disallow partial applications of functions on
values, but returning the correct type here is useful for code completion.

This introduces the required code completion callbacks which pass partially
parsed TypeReprs to code completion. These types can refer to generic function
parameters. Because we need to typecheck these types, we need to typecheck
generic parameters first. Because exposing fine-grained typechecker interface
just for code completion is bad, we create a function declaration based on the
limited information we have (i.e., just the function name and generic
parameters) and pass that to the typechecker. This approach (in theory) should
work uniformly for function decls and nominal type decls, but the nominal type
decl case is not tested yet. Eventually we will also want to use a similar
approach for normal parser recovery as well.

accessible at that time through the AST node, because the FuncDecl AST node was
not constructed yet.

line after a var decl with initializer would complete based on the initializer
expression.
These are technically valid completions, but confusing. Now this suggests
unqualified completions.
