f0e3459068 AST: Fix compiler_crasher regression from associated type where clause work 
New GenericTypeParamDecls should always be created with an
InvalidDepth, to prevent canonicalization before the generic
parameter list has been type checked.

6543405e2d [SR-4219] Resolve non-deterministic compiler crashes 
These were leftover from the #8059, which plugged a type variable leak
caused by type checking invalid default argument expressions.

1367b0cb36 Invalidate default argument exprs if typechecking fails 
If typechecking fails, the expression will have unsolved type variables
written into it.  This Crashes The Compiler.

In that case, there’s no reason to keep a tree of dangling references
around.  Detach the initializer expression from the AST, but continue
to typecheck it to see if we can get some useful diagnostics out of it.

e3d7ff954e [swiftc (74 vs. 5456)] Add crasher in swift::MetatypeType::get 
Add test case for crash triggered in `swift::MetatypeType::get`.

Current number of unresolved compiler crashers: 74 (5456 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 362)`](8c0e9d5525/lib/AST/ASTContext.cpp (L362)):

```
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");
  }

```

c1ad56f53f [swiftc (67 vs. 5458)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 67 (5458 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 1168)`](9a6f2ba0e5/lib/AST/Type.cpp (L1168)):

```
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 @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)`](df4b7752ff/lib/AST/DiagnosticEngine.cpp (L490)):

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

f74763d933 [Type checker] Teach areOverrideCompatibleSimple() to look at initializers. 
Apply the same is-generic check to initializers that we apply to
functions when establishing basic override compatibility. This is a
simple optimization for master, but fixes a crasher for Swift 3.1.

Fixes SR-4059.
