22aa032285 Sema: Clean up SE-0036 diagnostic a bit 
Suggest a fix-it for unqualified references to all static members
from instance context, not just enum elements.

Also, fix a small problem with the fix-it for replacing protocol
names with 'Self' inside extension bodies -- we didn't handle nested
functions properly.

62afa03eb9 Improve Foundation overlay to handle bridging subscripts and dictionary literals. 
SE-0072 took implicit bridging conversions away, which regressed the ability to express NSDictionaries as dictionary literals and index them using literal keys. Address this by changing the signature of init(dictionaryLiteral:) to use Hashable and Any, and by replacing the subscript from Objective-C with one using _Hashable that does the bridging on the user's behalf. This largely restores the QoI of working with NS collections.

e07e88706d Eliminate race in swift_bridgeErrorToNSError. 
Huge thanks to John for noting that 'consume' didn't provide the
guarantees we wanted, and to Michael G. for getting a TSan build up
and running to identify/verify this race.

It's possible that this is overlay strict, and that we only need to
look at the domain to ensure that the code and userInfo are
visible. However, TSan seems to prefix the form in this patch, so
we'll be more conservative for now.

Fixes rdar://problem/27541751.

75bd88968b SILGen: Allow extensions to define designated initializers of generic types 
Previously, if a generic type had a stored property with
a generic type and an initializer expression, we would
emit the expression directly in the body of each designated
initializer.

This is a problem if the designated initializer is defined
within an extension (even in the same source file), because
extensions have a different set of generic parameters and
archetypes.

Also, we've had bugs in the past where emitting an
expression multiple times didn't work properly. While these
might currently all be fixed, this is a tricky case to test
and it would be best to avoid it.

Fix both problems by emitting the initializer expression
inside its own function at the SIL level, and call the
initializer function from each designated initializer.

I'm using the existing 'variable initializer' mangling for this;
it doesn't seem to be used for anything else right now.

Currently, the default memberwise initializer does not use
this, because the machinery for emitting it is somewhat
duplicated and separate from the initializer expressions in
user-defined constructors. I'll clean this up in an upcoming
patch.

Fixes <https://bugs.swift.org/browse/SR-488>.

848b3eb6a3 [Driver] Make sure to rebuild dependents when a dirty file fails. (#3935) 
Otherwise we get into a situation like this:

1. Change made to the interface of file A.swift that also causes an
   error in A.swift.
2. Fixing the error in A.swift does not affect A.swift's interface.
3. File B.swift that depends on A.swift is not rebuilt, since the most
   recent change to A.swift did not change its interface.

To fix this, mark downstream files as needing to be rebuilt even when
a compilation job fails with errors. Additionally, attempt to be extra
conservative when there's a crash.

afdda3d107 Implement SE-0117. 
One minor revision: this lifts the proposed restriction against
overriding a non-open method with an open one.  On reflection,
that was inconsistent with the existing rule permitting non-public
methods to be overridden with public ones.  The restriction on
subclassing a non-open class with an open class remains, and is
in fact consistent with the existing access rule.

c9b73dacc2 [Sema] ban multi-arguments to tuple coercion 
Implements part of SE-0110. Single argument in closures will not be accepted if
there exists explicit type with a number of arguments that's not 1.

```swift
let f: (Int, Int) -> Void = { x in } // this is now an error
```

Note there's a second part of SE-0110 which could be considered additive,
which says one must add an extra pair of parens to specify a single arugment
type that is a tuple:

```swift
let g ((Int, Int)) -> Void = { y in } // y should have type (Int, Int)
```

This patch does not implement that part.

bb6c6740ca stdlib: fix a bug in ArraySlice.removeLast() when startIndex != 0 
ArraySlice.removeLast() only worked when startIndex was equal to zero.

This change fixes the bug, and uses the proper customization point for
the algorithm.

Fixes SR-1791, rdar://problem/26897658.
