[swiftc (38 vs. 5154)] Add crasher in swift::ArchetypeBuilder::mapTypeOutOfContext(...)

Add test case for crash triggered in `swift::ArchetypeBuilder::mapTypeOutOfContext(...)`.

Current number of unresolved compiler crashers: 38 (5154 resolved)

Assertion failure in [`lib/AST/ArchetypeBuilder.cpp (line 2086)`](https://github.com/apple/swift/blob/master/lib/AST/ArchetypeBuilder.cpp#L2086):

```
Assertion `!canType->hasTypeParameter() && "already have an interface type"' failed.

When executing: static swift::Type swift::ArchetypeBuilder::mapTypeOutOfContext(swift::ModuleDecl *, swift::GenericParamList *, swift::Type)
```

Assertion context:

```

Type ArchetypeBuilder::mapTypeOutOfContext(ModuleDecl *M,
                                           GenericParamList *genericParams,
                                           Type type) {
  auto canType = type->getCanonicalType();
  assert(!canType->hasTypeParameter() && "already have an interface type");
  if (!canType->hasArchetype())
    return type;

  assert(genericParams && "dependent type in non-generic context");

```
