f6cac54606 Replace concrete init(stringInterpolationSegment:)'s with generic ones 
Remove 16 concrete init(stringInterpolationSegment:) overloads and
replace them with 3 generic overloads, significantly reducing the
exponential blow-up from larger string interpolations.

Fixes rdar://problem/29389887.

7c8117301a In Swift 3 mode, allow "tuple unsplatting" in certain cases. (#7077) 
Swift 3.0 allowed constructing an enum or calling a function-typed
property with multiple arguments even when a single argument of tuple
type was expected. Emulate that in Swift 3 mode by wrapping in an
extra level of parentheses when the situation comes up.

Last vestiges of fallout from SE-0110. Hopefully last, anyway. A nice
follow-up to this commit might be to /warn/ in Swift 3 mode when this
happens.

Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 51 (5433 resolved)

/cc @lattner - just wanted to let you know that this crasher caused an assertion failure for the assertion `Result && "Case not implemented!"` added on 2011-03-22 by you in commit fd2bf74f :-)

Assertion failure in [`lib/AST/Type.cpp (line 1299)`](5fe6f33ae5/lib/AST/Type.cpp (L1299)):

```
Assertion `Result && "Case not implemented!"' failed.

When executing: swift::CanType swift::TypeBase::getCanonicalType()
```

Assertion context:

```c++
  }
  }

  // Cache the canonical type for future queries.
  assert(Result && "Case not implemented!");
  CanonicalType = Result;
  return CanType(Result);
}

```

0a828e363b [swiftc (48 vs. 5433)] Add crasher in swift::TypeBase::getContextSubstitutions 
Add test case for crash triggered in `swift::TypeBase::getContextSubstitutions`.

Current number of unresolved compiler crashers: 48 (5433 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!baseTy->isLValueType() && !baseTy->is<AnyMetatypeType>()` added on 2017-01-02 by you in commit 18adb532 :-)

Assertion failure in [`lib/AST/Type.cpp (line 3138)`](6f19169df2/lib/AST/Type.cpp (L3138)):

```
Assertion `!baseTy->isLValueType() && !baseTy->is<AnyMetatypeType>()' failed.

When executing: TypeSubstitutionMap swift::TypeBase::getContextSubstitutions(const swift::DeclContext *)
```

Assertion context:

```c++

TypeSubstitutionMap TypeBase::getContextSubstitutions(const DeclContext *dc) {
  assert(dc->isTypeContext());
  Type baseTy(this);

  assert(!baseTy->isLValueType() && !baseTy->is<AnyMetatypeType>());

  // The resulting set of substitutions. Always use this to ensure we
  // don't miss out on NRVO anywhere.
  TypeSubstitutionMap substitutions;

where we need to do a tuple-to-tuple conversion on a direct result;
if the result is wrapped in an Optional. So I believe this assert
is not right.

Fixes <https://bugs.swift.org/browse/SR-3706>.

cadc733c09 [swiftc (45 vs. 5433)] Add crasher in swift::Type::transformRec 
Add test case for crash triggered in `swift::Type::transformRec`.

Current number of unresolved compiler crashers: 45 (5433 resolved)

/cc @jckarter - just wanted to let you know that this crasher caused an assertion failure for the assertion `(conformingReplacementType->is<SubstitutableType>() || conformingReplacementType->is<DependentMemberType>()) && "replacement requires looking up a concrete conformance"` added on 2016-12-15 by you in commit 57d9ad0a :-)

Assertion failure in [`lib/AST/Type.cpp (line 2971)`](5e45c3920f/lib/AST/Type.cpp (L2971)):

```
Assertion `(conformingReplacementType->is<SubstitutableType>() || conformingReplacementType->is<DependentMemberType>()) && "replacement requires looking up a concrete conformance"' failed.

When executing: Optional<swift::ProtocolConformanceRef> swift::MakeAbstractConformanceForGenericType::operator()(swift::CanType, swift::Type, swift::ProtocolType *) const
```

Assertion context:

```c++
MakeAbstractConformanceForGenericType::operator()(CanType dependentType,
                                       Type conformingReplacementType,
                                       ProtocolType *conformedProtocol) const {
  assert((conformingReplacementType->is<SubstitutableType>()
          || conformingReplacementType->is<DependentMemberType>())
         && "replacement requires looking up a concrete conformance");
  return ProtocolConformanceRef(conformedProtocol->getDecl());
}

73771919d5 [swiftc (42 vs. 5433)] Add crasher in swift::constraints::ConstraintGraph::addConstraint(...) 
Add test case for crash triggered in `swift::constraints::ConstraintGraph::addConstraint(...)`.

Current number of unresolved compiler crashers: 42 (5433 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"` added on 2013-12-09 by you in commit 11794095 :-)

Assertion failure in [`lib/Sema/ConstraintGraph.cpp (line 50)`](de771d3819/lib/Sema/ConstraintGraph.cpp (L50)):

```
Assertion `impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index"' failed.

When executing: std::pair<ConstraintGraphNode &, unsigned int> swift::constraints::ConstraintGraph::lookupNode(swift::TypeVariableType *)
```

Assertion context:

```c++
std::pair<ConstraintGraphNode &, unsigned>
ConstraintGraph::lookupNode(TypeVariableType *typeVar) {
  // Check whether we've already created a node for this type variable.
  auto &impl = typeVar->getImpl();
  if (auto nodePtr = impl.getGraphNode()) {
    assert(impl.getGraphIndex() < TypeVariables.size() && "Out-of-bounds index");
    assert(TypeVariables[impl.getGraphIndex()] == typeVar &&
           "Type variable mismatch");
    return { *nodePtr, impl.getGraphIndex() };
  }

55c0e7401c Sema: Fix crash when @noescape or @autoclosure is applied to parameter 
In Swift 3, these attributes were changed to apply to the type,
and not the parameter. If they appear on the parameter, we would
go down a diagnostic code path.

When checking a generic function signature, we might not have a
contextual type for the parameter yet, so bail out instead of
crashing.

Add test case for crash triggered in `swift::DiagnosticEngine::emitDiagnostic`.

Current number of unresolved compiler crashers: 41 (5431 resolved)

/cc @jtbandes - just wanted to let you know that this crasher caused an assertion failure for the assertion `false && "encountered %error in diagnostic text"` added on 2016-11-19 by you in commit 32635696 :-)

Assertion failure in [`lib/AST/DiagnosticEngine.cpp (line 490)`](e9dd8107a9/lib/AST/DiagnosticEngine.cpp (L490)):

```
Assertion `false && "encountered %error in diagnostic text"' failed.

8c956c6f07 Disable a compiler_crasher test that is non-deterministic. 
The 28616-swift-parser-parseexprsequence-swift-diag-bool-bool.swift test
crashes due to a stack overflow. I had previously disabled it to get
through a master-next merge, so this just leaves it disabled. The only
change is to replace the Radar number with a better reason for why it is
disabled.

5f7dba7964 [swiftc (36 vs. 5431)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 36 (5431 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!base || !base->hasTypeParameter()` added on 2016-12-25 by you in commit 71df32fd :-)

Assertion failure in [`lib/Sema/OverloadChoice.h (line 108)`](9bdd3d216d/lib/Sema/OverloadChoice.h (L108)):

```
Assertion `!base || !base->hasTypeParameter()' failed.

When executing: swift::constraints::OverloadChoice::OverloadChoice(swift::Type, swift::ValueDecl *, bool, swift::FunctionRefKind)
```

Assertion context:

```c++

  OverloadChoice(Type base, ValueDecl *value, bool isSpecialized,
                 FunctionRefKind functionRefKind)
    : BaseAndBits(base, isSpecialized ? IsSpecializedBit : 0),

671d470322 [Diagnostics] Don't attempt member lookup if base type has unresolved type parameters 
If there are unresolved generic parameters present and we are trying
to diagnose problems related to initializer call, it makes sense to
check argument expression first, which might be erroneous and then move
on to the ambiguity checking instead of trying to lookup possible
constructors directly.
