5f7dba7964 [swiftc (36 vs. 5431)] Add crasher in swift::Expr::walk(...) 
Add test case for crash triggered in `swift::Expr::walk(...)`.

Current number of unresolved compiler crashers: 36 (5431 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!base || !base->hasTypeParameter()` added on 2016-12-25 by you in commit 71df32fd :-)

Assertion failure in [`lib/Sema/OverloadChoice.h (line 108)`](9bdd3d216d/lib/Sema/OverloadChoice.h (L108)):

```
Assertion `!base || !base->hasTypeParameter()' failed.

When executing: swift::constraints::OverloadChoice::OverloadChoice(swift::Type, swift::ValueDecl *, bool, swift::FunctionRefKind)
```

Assertion context:

```c++

  OverloadChoice(Type base, ValueDecl *value, bool isSpecialized,
                 FunctionRefKind functionRefKind)
    : BaseAndBits(base, isSpecialized ? IsSpecializedBit : 0),
      TheFunctionRefKind(functionRefKind) {
    assert(!base || !base->hasTypeParameter());
    assert((reinterpret_cast<uintptr_t>(value) & (uintptr_t)0x03) == 0 &&
           "Badly aligned decl");

    DeclOrKind = reinterpret_cast<uintptr_t>(value);
  }
```

671d470322 [Diagnostics] Don't attempt member lookup if base type has unresolved type parameters 
If there are unresolved generic parameters present and we are trying
to diagnose problems related to initializer call, it makes sense to
check argument expression first, which might be erroneous and then move
on to the ambiguity checking instead of trying to lookup possible
constructors directly.

ecfea608db [Type checker] Classify the various optional conversion kinds. 
1efafbcd9b restricted our classification
of various optional-related conversions (implicit forcing of IUOs,
optional-to-optional conversions, value-to-optional conversions) to
produce a single potential classification. However, in the presence of
type variables, we cannot always determine which particular conversion
restriction might apply. Prior to 1efafb, we produced too many
options; after 1efafb, we produced too few. Here, enumerate a more
bounded (but complete) set of potential conversions, taking into
account embedded type variables.

This is a better fix for rdar://problem/29977523 than simply reverting
1efafb, because it bounds the set of optional conversions we attempt.

2612603b12 master-next: temporarily disable a failing test 
This test consistently crashes with a stack overflow when I run the test
directly, but when run from the test harness with the master-next branch,
it fails to crash. I tried doubling the number of braces but that did not
help. Tracking resolution of this in rdar://problem/30055108

6f217dbe2a [ConstraintSystem] Don't attempt to solve candidates which have closures. 
While shrinking constraint system, avoid candidates which contain
closures inside, because closure expressions require special handling
and allow no rollback.

488fc0fad5 [QoI] Cleanup AST after trying to shrink constraint system of invalid expression 
Since `ConstraintSystem::shrink` is going to attempt to type-check
sub-expressions separately it's essential to clean-up AST if constraint
generation or solving of the such expressions fails, otherwise if
such solving resulted in creation of implicit expression type variables
might leak to the outside.

The fact that they consistently crash on Linux is not assured,
since the root cause of all of these is memory corruption.

ab14d46431 This test only crashes on some linux hosts. Disabled it. (#6700) 
compiler_crashers/28543-unreachable-executed-at-swift-include-swift-ast-typevisitor-h-39.swift
occasionally does not crash on the public CI ubuntu 14.04 bot.

Marking it REQUIRES: deterministic-behavior, which effectively disables it.

b79b482974 This test only crashes on some linux hosts. Disabled it. (#6691) 
compiler_crashers/28634-anonymous-namespace-verifier-verifychecked-swift-type-llvm-smallptrset-swift-arc.swift
does not crash on the public CI ubuntu 14.04 bot.

I'm disabling it because it's been failing all day and I don't know how to
restrict a test based on the host. The target triple is the same
in the crashing and noncrashing case.

bd77719874 [swiftc (57 vs. 5396)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 57 (5396 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 1292)`](https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L1292):

```
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);
}

```

49cd8b1cf9 [swiftc (52 vs. 5396)] Add crasher in swift::constraints::ConstraintSystem::performMemberLookup 
Add test case for crash triggered in `swift::constraints::ConstraintSystem::performMemberLookup`.

Current number of unresolved compiler crashers: 52 (5396 resolved)

/cc @slavapestov - just wanted to let you know that this crasher caused an assertion failure for the assertion `!base || !base->hasTypeParameter()` added on 2016-12-25 by you in commit 71df32fd :-)

Assertion failure in [`lib/Sema/OverloadChoice.h (line 108)`](https://github.com/apple/swift/blob/master/lib/Sema/OverloadChoice.h#L108):

```
Assertion `!base || !base->hasTypeParameter()' failed.

When executing: swift::constraints::OverloadChoice::OverloadChoice(swift::Type, swift::ValueDecl *, bool, swift::FunctionRefKind)
```

Assertion context:

```

  OverloadChoice(Type base, ValueDecl *value, bool isSpecialized,
                 FunctionRefKind functionRefKind)
    : BaseAndBits(base, isSpecialized ? IsSpecializedBit : 0),
      TheFunctionRefKind(functionRefKind) {
    assert(!base || !base->hasTypeParameter());
    assert((reinterpret_cast<uintptr_t>(value) & (uintptr_t)0x03) == 0 &&
           "Badly aligned decl");

    DeclOrKind = reinterpret_cast<uintptr_t>(value);
  }
```
