5428178b58 [swiftc (138 vs. 5198)] Add crasher in swift::Expr::propagateLValueAccessKind 
Add test case for crash triggered in `swift::Expr::propagateLValueAccessKind`.

Current number of unresolved compiler crashers: 138 (5198 resolved)

Assertion failure in [`lib/AST/Expr.cpp (line 235)`](https://github.com/apple/swift/blob/master/lib/AST/Expr.cpp#L235):

```
Assertion `E->getType()->isAssignableType() && "setting access kind on non-l-value"' failed.

When executing: void swift::Expr::propagateLValueAccessKind(swift::AccessKind, bool)::PropagateAccessKind::visit(swift::Expr *, swift::AccessKind)
```

Assertion context:

```
    void visit(Expr *E, AccessKind kind) {
      assert((AllowOverwrite || !E->hasLValueAccessKind()) &&
             "l-value access kind has already been set");

      assert(E->getType()->isAssignableType() &&
             "setting access kind on non-l-value");
      E->setLValueAccessKind(kind);

      // Propagate this to sub-expressions.
      ASTVisitor::visit(E, kind);
    }
```

887fb3750a [Parse] Fix range containment problem in statement condition 
For constructing the dummy expression for missing initializer,
use the end location of the pattern instead of the location of the
current token.

Previous behavior used to build AST like:

  { if let x [eof]
       |---|       Pattern range
             |---| Dummy introducer range
    |------------| IfStmt range
  |--------|       BraceStmt range

Now:

  { if let x [eof]
       |---|       Pattern range
           |       Dummy introducer range
    |------|       IfStmt range
  |--------|       BraceStmt range

It's not consistently crashing, which means the bug might be reading from uninitialized memory, but more immediately it's mucking with our CI.

dfea7ee441 [Sema] Skip UNCHECKED_EXPRs in ErrorHandlingWalker 
On rare occasions, malformed programs can allow an UNCHECKED_EXPR (e.g. ArrowExpr) to escape type checking. The erroneous expression may have sub-expressions which aren't fully typechecked, so we can't safely visit them.

126f2451db [swiftc (118 vs. 5184)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 118 (5184 resolved)

Assertion failure in [`lib/AST/Type.cpp (line 1286)`](https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L1286):

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

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

Assertion context:

```
  }
  }

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

```
