712052bc9a [QoI] Mark inactive constraints as retired after removing 
This makes sure that removed constraints are returned back to the
system after current run, otherwise only constraint graph would
get them back since it has its own scope.

25e623addb Don't resolve a generic type parameter type from null environments 
The generic environment of a GenericTypeToArchetypeResolver may be
`nullptr`, as returned by DeclContext::getGenericEnvironmentOfContext,
during prechecking of closure expressions at the necessarily non-generic
top level.

Fixes a couple of crashers.

330c2d96e6 Make the lexer UTF-8 RFC 3629 correct re: prefix octets 
RFC 2279 states that, in UTF-8:
"The octet values FE and FF never appear."

RFC 3629 states that, in UTF-8:
"The octet values C0, C1, F5 to FF never appear."

Generalize the check to advance past invalid starting bytes for
a UTF-8 sequence to fix a crash in the lexer.

fc678740db [code-completion] Avoid a tentantive parse when in code-completion mode and make sure CodeCompletionExpr has a token range. 
The tentantive parse is used for diagnostic purposes but can cause code-completion to delay the same decl twice.
The range of CodeCompletionExpr was previously character range which invalidated invariants of the AST.

a317c6ac02 [swiftc (136 vs. 5234)] Add crasher in swift::TypeBase::getCanonicalType(...) 
Add test case for crash triggered in `swift::TypeBase::getCanonicalType(...)`.

Current number of unresolved compiler crashers: 136 (5234 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 1312)`](https://github.com/apple/swift/blob/master/lib/AST/Type.cpp#L1312):

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

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

Assertion context:

```
  }

  llvm_unreachable("Unknown type kind");
}

TypeBase *ParenType::getSinglyDesugaredType() {
  return getUnderlyingType().getPointer();
}

TypeBase *NameAliasType::getSinglyDesugaredType() {
  auto *TAD = getDecl();
```

1a991da16d AST: Assign interface types to ParamDecls 
First, ensure all ParamDecls that are synthesized from scratch are given
both a contextual type and an interface type.

For ParamDecls written in source, add a new recordParamType() method to
GenericTypeResolver. This calls setType() or setInterfaceType() as
appropriate.

Interestingly enough a handful of diagnostics in the test suite have
improved. I'm not sure why, but I'll take it.

The ParamDecl::createUnboundSelf() method is now only used in the parser,
and no longer sets the type of the self parameter to the unbound generic
type. This was wrong anyway, since the type was always being overwritten.
This allows us to remove DeclContext::getSelfTypeOfContext().

Also, ensure that FuncDecl::getBodyResultTypeLoc() always has an interface
type for synthesized declarations, eliminating a mapTypeOutOfContext()
call when computing the function interface type in configureInterfaceType().

Finally, clean up the logic for resolving the DynamicSelfType. We now
get the interface or contextual type of 'Self' via the resolver, instead
of always getting the contextual type and patching it up inside
configureInterfaceType().

91e8a0ccdb [QoI] When adding archetype requirements don't expect all of the members to be resolved 
Some of the type members might be unresolved because they are misspelled or
do not exist (represented by DependentMemberType), so when trying to add
requirements to the nested types don't expect that all of the members have
their associated types resolved.

Resolves: <rdar://problem/28235248>.

c98295357c [Archetype builder] Simplify handling of typealiases in protocols. 
PotentialArchetype::getNestedType() was effectively reimplementing a
simplified form of mapTypeOutOfContext(), missing some cases in the
process. Just use mapTypeOutOfContext() and resolveArchetype(). While
here, stop re-implementing the addSameType* operations; just call them
directly. With these changes, we no longer need the "typealias in
protocol is too complex" diagnostic.

Eliminates another use of getSelfTypeInContext().

277608a69b Print and parse SILBoxTypes with a new syntax. 
Use a syntax that declares the layout's generic parameters and fields,
followed by the generic arguments to apply to the layout:

  { var Int, let String } // A concrete box layout with a mutable Int
                          // and immutable String field
  <T, U> { var T, let U } <Int, String> // A generic box layout,
                                        // applied to Int and String
                                        // arguments

2ff9994313 Sema: Improve circularity checks 
The previous patches regressed a test where we used to diagnose
(poorly) a circular associated type, like so:

  associatedtype e: e

With the error "inheritance from non-protocol, non-class type 'e'".

This error went away, because we end up not setting the interface
type of the associated type early enough. Instead, we return an
ErrorType from resolveTypeInContext() and diagnose nothing.

With this patch, emit a diagnostic at the point where the ErrorType
first appears.

Also, remove the isRecursive() bit from AssociatedTypeDecl, and
remove isBeingTypeChecked() which duplicates a bit with the same
name in Decl.

This reverts commit 231fb5e054.

This test was failing the last time we updated the stable branches
of LLVM/Clang so it was disabled. No one remembers what was the
problem, so try reenabling it to see if anything breaks.

589b469484 [AST] Extend a hack to work around broken circular inheritance checking. 
Extending this hack recovers a regression in a previously-fixed
compiler crasher (#26725), and fixes two more compiler crashers. So,
despite it's utter lack of principle, it's progress.
