...
Add test case for crash triggered in `swift::TypeChecker::resolveDeclRefExpr`.
Current number of unresolved compiler crashers: 30 (5390 resolved)
/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasInterfaceType() && "No interface type was set"` added on 2016-12-04 by you in commit c1a21613https://github.com/apple/swift/blob/master/lib/AST/Decl.cpp#L1678 ):
```
Assertion `hasInterfaceType() && "No interface type was set"' failed.
When executing: swift::Type swift::ValueDecl::getInterfaceType() const
```
Assertion context:
```
bool ValueDecl::hasInterfaceType() const {
return !TypeAndAccess.getPointer().isNull();
}
Type ValueDecl::getInterfaceType() const {
assert(hasInterfaceType() && "No interface type was set");
return TypeAndAccess.getPointer();
}
void ValueDecl::setInterfaceType(Type type) {
// lldb creates global typealiases with archetypes in them.

[swiftc (27 vs. 5389)] Add crasher in swift::decomposeParamType
...
Add test case for crash triggered in `swift::decomposeParamType`.
Current number of unresolved compiler crashers: 27 (5389 resolved)
/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `argumentLabels.size() == 1` added on 2016-07-25 by you in commit 847b7824https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L837 ):
```
Assertion `argumentLabels.size() == 1' failed.
When executing: SmallVector<swift::CallArgParam, 4> swift::decomposeArgType(swift::Type, ArrayRef<swift::Identifier>)
```
Assertion context:
```
// Just inject this parameter.
assert(result.empty());
CallArgParam argParam;
argParam.Ty = type;
assert(argumentLabels.size() == 1);
argParam.Label = argumentLabels[0];
result.push_back(argParam);

Sema: Tighten up name lookup routines to not look through metatypes/lvalues/etc
...
Previously all of the following would strip off varying amounts of
MetatypeType, LValueType, InOutType, DynamicSelfType, etc:
- ConstraintSystem::performMemberLookup()
- ConstraintSystem::lookupMember()
- TypeChecker::lookupMember()
- DeclContext::lookupQualified()
- Type::getContextSubstitutions()
The problem is that the higher level methods that took a lookup type
would call the lower level methods, and post-process the result using
the given lookup type. Since different levels of sugar were stripped,
it made the code hard to reason about and opened up edge cases, eg
if a DynamicSelfType or InOutType appears where we didn't expect it.
Since filtering out static/instance and mutating/nonmutating members
is done at higher levels, there's no reason for these name lookup
operations to accept anything other than nominal types, existentials
and archetypes.
Make this so with assertions, and deal with the fallout.

AST: Return abstract conformance for UnresolvedType
...
We "fake" a conformance of UnresolvedType to any protocol.
Instead of returning a concrete conformance, return an
abstract conformance. The concrete conformance had several
problems leading to further crashes:
- The DC was set to a module, not a type declaration context,
since there is not type declaration context here.
- The conformance was marked complete even though it was missing
inherited conformances.

ASTVerifier: Don't check Override attribute if we haven't done early attribute validation
...
If the 'override' attribute appears on an invalid decl,
it is removed at the start of typeCheckDecl(). However if
the decl is nested inside a multi-statement closure which
is invalid for other reasons, we may have validated it
but not type checked it, in which case we don't want to
crash in the verifier.

Sema: Fix closeExistential() in CSApply with invalid direct call of metatype
...
When we have a value 'p' of type 'P.Type' for some protocol 'P',
we require the user to write 'p.init()' rather than 'p()' to
construct an instance of a concrete type conforming to 'P'.
If they write 'p()', we suggest a fixit to insert '.init',
however if there is also a subsequent member access on the
result, for example 'p().foo', we would crash.
Another invalid case that used to crash is when you construct
a protocol metatype directly and then access a member of it,
eg. 'P().foo'.

[Diagnostics] When checking AssignExpr properly diagnose destination
...
Currently if destination is unresolved instead of trying to re-typecheck
it again and diagnose structural problems which led to such outcome, it
gets completely ignored in favor of trying to type-check source without
contextual type. That leads to missed diagnostic opportunities, which
results in problems on AST verification and SIL generation stages, and
generally missleading errors e.g. `.x = 0`.
