a22c58574c [swiftc (35 vs. 5565)] Add crasher in swift::GenericSignatureBuilder::Constraint 
Add test case for crash triggered in `swift::GenericSignatureBuilder::Constraint`.

Current number of unresolved compiler crashers: 35 (5565 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `nestedPAByName && "Didn't find the associated type we wanted"` added on 2017-03-23 by you in commit 8bd863e6 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 347)`](bf7838c9cf/lib/AST/GenericSignatureBuilder.cpp (L347)):

```
Assertion `nestedPAByName && "Didn't find the associated type we wanted"' failed.

When executing: PotentialArchetype *replaceSelfWithPotentialArchetype(PotentialArchetype *, swift::Type)
```

Assertion context:

```c++

      if (auto result = findNested(otherBasePA))
        return result;
    }

    assert(nestedPAByName && "Didn't find the associated type we wanted");
    return nestedPAByName;
  }

  assert(depTy->is<GenericTypeParamType>() && "missing Self?");
  return selfPA;
```

bebc1821ea [swiftc (34 vs. 5565)] Add crasher in swift::GenericSignature::getConformanceAccessPath 
Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 34 (5565 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `conforms != equivClass->conformsTo.end()` added on 2017-03-06 by you in commit eaee4add :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 881)`](1afcafcd24/lib/AST/GenericSignature.cpp (L881)):

```
Assertion `conforms != equivClass->conformsTo.end()' failed.

When executing: auto swift::GenericSignature::getConformanceAccessPath(swift::Type, swift::ProtocolDecl *, swift::ModuleDecl &)::(anonymous class)::operator()(swift::GenericSignature *, const RequirementSource *, swift::ProtocolDecl *, swift::Type) const
```

Assertion context:

```c++
      auto equivClass = pa->getOrCreateEquivalenceClass();

      // Find the conformance of this potential archetype to the protocol in
      // question.
      auto conforms = equivClass->conformsTo.find(conformingProto);
      assert(conforms != equivClass->conformsTo.end());

      // Compute the root type, canonicalizing it w.r.t. the protocol context.
      auto inProtoSig = inProtocol->getGenericSignature();
      auto conformsSource = getBestRequirementSource(conforms->second);
      Type localRootType = conformsSource->getRootPotentialArchetype()
```

0b0f032d8f [swiftc (32 vs. 5563)] Add crasher in swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete 
Add test case for crash triggered in `swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete`.

Current number of unresolved compiler crashers: 32 (5563 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `conformance->isConcrete() || Concrete->isExistentialType()` added on 2017-02-23 by you in commit cbbf4154 :-)

Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 3371)`](c21699b4e5/lib/AST/GenericSignatureBuilder.cpp (L3371)):

```
Assertion `conformance->isConcrete() || Concrete->isExistentialType()' failed.

When executing: ConstraintResult swift::GenericSignatureBuilder::addSameTypeRequirementToConcrete(swift::GenericSignatureBuilder::PotentialArchetype *, swift::Type, const swift::GenericSignatureBuilder::RequirementSource *)
```

Assertion context:

```c++
    }

    conformances.insert({protocol, *conformance});

    // Abstract conformances are acceptable for existential types.
    assert(conformance->isConcrete() || Concrete->isExistentialType());

    // Update the requirement source now that we know it's concrete.
    // FIXME: Bad concrete source info.
    auto concreteSource = Source->viaConcrete(*this,
                                              conformance->isConcrete()
```

Add test case for crash triggered in `swift::TypeChecker::resolveIdentifierType`.

Current number of unresolved compiler crashers: 30 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `memberType && "Received null dependent member type"` added on 2017-05-21 by you in commit 0eac6f017 :-)

Assertion failure in [`lib/Sema/TypeCheckType.cpp (line 1389)`](2808583c6a/lib/Sema/TypeCheckType.cpp (L1389)):

```
Assertion `memberType && "Received null dependent member type"' failed.

When executing: swift::Type resolveNestedIdentTypeComponent(swift::TypeChecker &, swift::DeclContext *, swift::Type, swift::SourceRange, swift::ComponentIdentTypeRepr *, TypeResolutionOptions, bool, swift::GenericTypeResolver *, UnsatisfiedDependency *)

Assertion context:

```c++
  // If the parent is a type parameter, the member is a dependent member,
  // and we skip much of the work below.

Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 28 (5563 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `hasConformanceInSignature(inProtocol->getRequirementSignature(), subjectType, conformingProto) && "missing explicit conformance in requirement signature"` added on 2017-03-08 by you in commit 1f8b0f9b :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 846)`](36f689d1d2/lib/AST/GenericSignature.cpp (L846)):

c924d6373c [swiftc (25 vs. 5563)] Add crasher in swift::TypeChecker::substMemberTypeWithBase 
Add test case for crash triggered in `swift::TypeChecker::substMemberTypeWithBase`.

Current number of unresolved compiler crashers: 25 (5563 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `(!Parent || Parent->is<NominalType>() || Parent->is<BoundGenericType>() || Parent->is<UnboundGenericType>()) && "parent must be a nominal type"` added on 2016-11-03 by you in commit 5780a9f52 :-)

Assertion failure in [`lib/AST/ASTContext.cpp (line 2841)`](a020ccc25f/lib/AST/ASTContext.cpp (L2841)):

```
Assertion `(!Parent || Parent->is<NominalType>() || Parent->is<BoundGenericType>() || Parent->is<UnboundGenericType>()) && "parent must be a nominal type"' failed.

When executing: static swift::NominalType *swift::NominalType::get(swift::NominalTypeDecl *, swift::Type, const swift::ASTContext &)
```

Assertion context:

```c++

  return newType;
}

NominalType *NominalType::get(NominalTypeDecl *D, Type Parent, const ASTContext &C) {
  assert((isa<ProtocolDecl>(D) || !D->getGenericParams()) &&
         "must be a non-generic type decl");
  assert((!Parent || Parent->is<NominalType>() ||
          Parent->is<BoundGenericType>() ||
          Parent->is<UnboundGenericType>()) &&

773d7b3225 Sema: Remove more methods from GenericTypeResolver 
resolveGenericTypeParamType(), resolveTypeOfDecl() and
resolveTypeOfContext() would all take the type of a
declaration, and optionally map it into context.

Replace them with a mapTypeIntoContext() that takes a
type and either returns it verbatim or maps it into
context.

Add test case for crash triggered in `swift::TypeChecker::checkDeclAttributesEarly(...)`.

Current number of unresolved compiler crashers: 37 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `loc.isValid() && "Diagnosing attribute with invalid location"` added on 2017-04-22 by you in commit 25ce6fa2 :-)

Assertion failure in [`lib/Sema/TypeCheckAttr.cpp (line 39)`](df10b0fe02/lib/Sema/TypeCheckAttr.cpp (L39)):

```
Assertion `loc.isValid() && "Diagnosing attribute with invalid location"' failed.

When executing: void (anonymous namespace)::diagnoseAndRemoveAttr(swift::TypeChecker &, swift::Decl *, swift::DeclAttribute *, ArgTypes &&...) [ArgTypes = <swift::Diag<> &>]
```

Assertion context:

```c++
  void diagnoseAndRemoveAttr(TypeChecker &TC, Decl *D, DeclAttribute *attr,
                             ArgTypes &&...Args) {
    assert(!D->hasClangNode() && "Clang imported propagated a bogus attribute");
    if (!D->hasClangNode()) {
      SourceLoc loc = attr->getLocation();
      assert(loc.isValid() && "Diagnosing attribute with invalid location");
      if (loc.isInvalid()) {

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `ty->getNominalOrBoundGenericNominal() || ty->is<DynamicSelfType>() || ty->isExistentialType() || ty->is<ArchetypeType>()` added on 2014-02-25 by you in commit 6a532e05c :-)

Assertion failure in [`lib/Sema/CSApply.cpp (line 7121)`](5c1859e98a/lib/Sema/CSApply.cpp (L7121)):

7ef9041111 [swiftc (30 vs. 5544)] Add crasher in swift::GenericSignature::getConformanceAccessPath 
Add test case for crash triggered in `swift::GenericSignature::getConformanceAccessPath`.

Current number of unresolved compiler crashers: 30 (5544 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `inProtocol->isRequirementSignatureComputed() && "missing signature"` added on 2017-03-08 by you in commit 1f8b0f9b :-)

Assertion failure in [`lib/AST/GenericSignature.cpp (line 857)`](aae1b681e7/lib/AST/GenericSignature.cpp (L857)):

```
Assertion `inProtocol->isRequirementSignatureComputed() && "missing signature"' failed.

When executing: auto swift::GenericSignature::getConformanceAccessPath(swift::Type, swift::ProtocolDecl *, swift::ModuleDecl &)::(anonymous class)::operator()(swift::GenericSignature *, const RequirementSource *, swift::ProtocolDecl *, swift::Type) const
```

Assertion context:

```c++

      // Canonicalize this step with respect to the requirement signature.
      if (!inProtocol->isRequirementSignatureComputed()) {
        inProtocol->computeRequirementSignature();
        assert(inProtocol->isRequirementSignatureComputed() &&
               "missing signature");
      }

      // Get a generic signature builder for the requirement signature. This has
      // the requirement we need.
      auto reqSig = inProtocol->getRequirementSignature();
```

63bc717963 Error when one associated type is constrained to another. (#10053) 
(...is constrained to be a subtype of another)

Previously the compiler would just mark the entry in the inheritance
clause invalid and move on without emitting any errors; in certain
circumstances in no-asserts builds this could actually lead to
everything working "correctly" if all conforming types happened to
pick the same concrete type for both associated types. In Swift 4 this
can actually be enforced with a same-type requirement, which will
guarantee that the two associated types are the same even in generic
contexts.

This fix avoids assertions and crashes, but the diagnostic is still
incorrect, and in the simple case of the inheritance clause it's
redundant. Doing something better and possibly even downgrading it to
a warning in Swift 3 mode is tracked by rdar://problem/32409449.

Initial patch by Slava, fixed up by me.
