f1f9e88360 Cache expression types in failure diagnosis. 
After we call into typeCheckExpression() we need to cache the
resulting types in the constraint system type map because we later
call into code that reads the types out of the type map.

Fixes rdar://problem/30376186 as well as a couple crashers.

4ffb4a443f [swiftc (52 vs. 5454)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 52 (5454 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 1304)`](ee4100ca8a/lib/AST/Type.cpp (L1304)):

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

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

Assertion context:

```c++
    break;
  }
  }

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

```

f2b3aea0b5 [swiftc (50 vs. 5453)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 50 (5453 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 1304)`](db98e1cc95/lib/AST/Type.cpp (L1304)):

```
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);
}

/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)`](efc870a2d9/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);
}

```

4fd1ccfe43 [swiftc (38 vs. 5451)] Add crasher in swift::MetatypeType::get 
Add test case for crash triggered in `swift::MetatypeType::get`.

Current number of unresolved compiler crashers: 38 (5451 resolved)

/cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `CurrentConstraintSolverArena && "No constraint solver active?"` added on 2012-11-14 by you in commit 2183b57fa :-)

Assertion failure in [`lib/AST/ASTContext.cpp (line 358)`](c2775070e2/lib/AST/ASTContext.cpp (L358)):

```
Assertion `CurrentConstraintSolverArena && "No constraint solver active?"' failed.

When executing: swift::ASTContext::Implementation::Arena &swift::ASTContext::Implementation::getArena(swift::AllocationArena)
```

Assertion context:

```c++
    switch (arena) {
    case AllocationArena::Permanent:
      return Permanent;

    case AllocationArena::ConstraintSolver:
      assert(CurrentConstraintSolverArena && "No constraint solver active?");
      return *CurrentConstraintSolverArena;
    }
    llvm_unreachable("bad AllocationArena");
  }

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);
}

```
