- Fix a diagnostic to not include redundant ''s around a type name.
- Rework CleanupIllFormedExpression to be simpler and to not
unconditionally destroy data when it doesn't. This makes a code
completion test a bit more precise.
- Completely revamp getTypeOfIndependentSubExpression, to return the
subexpression produced by type checking instead of just a type. This
is important for cases when type checking changes the root of the AST
(e.g. resolving an unresolved_dot_expr) and allows us to eliminate
grungy and unsafe recovery code that was in place to work around this.
The last point makes the examples in Constraints/lvalues.swift better (giving
a somewhat generic error instead of an specific-but-incorrect error that 'z'
is immutable), but more importantly, it fixes a class of crashers like
<rdar://problem/21369926> Malformed Swift Enums crash playground service
where we'd end up with a LiteralExpr typed as Int instead of a Builtin integer
type of some sort.

First, fix a case of type checking an expression twice, which is against
the design of the type checker. We hit this because we can type check
the "context" in
let x = foo.#^COMPLETE^#
and then type check the "parsed expression", which is contained in the
context here.
Second, make the hack from rdar://20738314 more robust so that if we
*do* double typecheck for some reason we won't just choke on an
AutoClosureExpr. I filed rdar://21466394 to audit for other cases of
double typechecking and remove this hack.

Completions for calling functions will now show 'throws' in the
description text so that users can differentiate throwing and
non-throwing calls. We don't insert this into the source text, since
it's not part of the call syntax.

protocol P { typealias T; func foo() -> T }
func invalid(x: P) { x.#^COMPLETE^#
We were trying to access a null Type created because the associated type
doesn't make sense in the protocol type P (we can only use P as a
generic constraint, but it shouldn't crash code completion if we use it
incorrectly).
For rdar://problem/20305938
Swift SVN r28588
We were asserting (and doing the wrong thing) when trying to code
complete
nil #^HERE^#
The issue is that we tried to apply a solution to the expression that
contained free type variables (converted to generic parameters). This
trips us up when we expect the new type to conform to protocols. In code
completion we generally only need the type of the expression, so this
commit switches to getting that more explicitly. That said, this did
cause us to drop non-API parameter names in call patterns after an
opening '(' in some cases (covered by rdar://20962472).
Thanks to Doug for suggesting this solution!

After this change,
extension P where WHERE1 { final func foo() {} }
extension P where WHERE2 { final func bar() { #^COMPLETE_HERE^#
will complete foo() if and only if WHERE2 is complatible with WHERE1.

Curried function parameters (i.e., those past the first written
parameter list) default to having argument labels (which they always
have), but any attempt to change or remove the argument labels would
fail. Use the fact that we keep both the argument labels and the
parameter names in patterns to generalize our handling of argument
labels to address this problem.
The IDE changes are due to some positive fallout from this change: we
were using the body parameters as labels in code completions for
subscript operations, which was annoying and wrong.
Fixes rdar://problem/17237268.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

Introduce the new BooleanLiteralConvertible protocol for Boolean
literals. Take "true" and "false" as real keywords (which is most of the
reason for the testsuite churn). Make Bool BooleanLiteralConvertible
and the default Boolean literal type, and ObjCBool
BooleanLiteralConvertible. Fixes <rdar://problem/17405310> and the
recent regression that made ObjCBool not work with true/false.
Swift SVN r19728
We want to complete foo(p: (Int, Int)) as foo({#(p): (Int, Int)#}), not
as foo({#Int#}, {#Int#}). Also, make initializers go through the
function parameter code path rather than the enum one, since we don't
want to recursively find parameters in tuples.

instead, so it picks up substituted types. BodyParamPatterns is now only
used for the local non-api parameter name.
Consolidate the two variations of addFunctionCallPattern() into one function.
Update the tests accordingly.

if there's no parameter API name. This is for display purposes only.
Update all relevant tests accordingly.
This addresses <rdar://problem/16768768>.
For example:
class X {
func f(a: Int, b: Int) { }
}
Would previously display like this in code completion in Xcode:
f(<#Int#>, b: <#Int#>)
The local parameter name, while not API, often still conveys meaning
to the user. So it's now included like this:
f(<#a: Int#>, b: <#Int#>)
Swift SVN r18403
The leading paren is included for display purposes only, not inserted
in the code if already present. It makes the displayed text in the
code completion list symmetrical with respect to open/close parens.
Add markups when printing annotation chunks so it becomes testable.
Update tests accordingly, and include tests for leading parens.
This addresses <rdar://problem/16918310>.
