[Type checker] Use call argument matching even with type variables on the left-hand side.
Rather than using a specialized matching rule in the type checker that depends on having default arguments in types, use call argument matching consistently. Note #1: This (correctly) breaks some existing code that depends on inferring a parameter type of () for a single-argument parameter from a no-argument function type(). Note #2: This pessimizes a code completion test, where the code completion engine seems to depend on some quirks of argument matching. The "type relationship" matching needs non-trivial work. |

AST: Slightly change meaning of NominalTypeDecl::getDeclaredType()
Consider this code:
struct A<T> {
struct B {}
struct C<U> {}
}
Previously:
- getDeclaredType() of 'A.B' would give 'A<T>.B'
- getDeclaredTypeInContext() of 'A.B' would give 'A<T>.B'
- getDeclaredType() of 'A.C' would give 'A<T>.C'
- getDeclaredTypeInContext() of 'A.C' would give 'A<T>.C<U>'
This was causing problems for nested generics. Now, with this change,
- getDeclaredType() of 'A.B' gives 'A.B' (*)
- getDeclaredTypeInContext() of 'A.B' gives 'A<T>.B'
- getDeclaredType() of 'A.C' gives 'A.C' (*)
- getDeclaredTypeInContext() of 'A.C' gives 'A<T>.C<U>'
(Differences marked with (*)).
Also, this change makes these accessors fully lazy. Previously,
only getDeclaredTypeInContext() and getDeclaredIterfaceType()
were lazy, whereas getDeclaredType() was built from validateDecl().
Fix a few spots where the return value wasn't being checked
properly.
These functions return ErrorType if a circularity was detected via
the generic parameter list, or if the extension did not resolve.
They return Type() if the extension cannot be resolved *yet*.
This is pretty subtle, and I'll need to do another pass over
callers of these functions at some point. Many of them should be
moved over to use getSelfInContext(), getSelfOfContext() and
getSelfInterfaceType() instead.
Finally, this patch consolidates logic for diagnosting invalid
nesting of types.
The parser had some code for protocols in bad places and bad things
inside protocols, and Sema had several different bail-outs for
bad things in protocols, nested generic types, and stuff nested
inside protocol extensions.
Combine all of these into a single set of checks in Sema. Note
that we no longer give up early if we find invalid nesting.
Leaving decls unvalidated and un-type-checked only leads to
further problems. Now that all the preliminary crap has been
fixed, we can go ahead and start validating these funny nested
decls, actually fixing some crashers in the process.

Sema: Clean up some code duplication when validating generic type signatures
Every call to validateGenericTypeSignature() had the same
boilerplate following; move the common logic into that
function.
As one might expect, each callsite had slight variants on
the same underlying logic -- this makes them consistent.
Also, this slightly widens the scope during which
GenericTypeDecl::isValidatingGenericSignature() returns
true.
Interesting, that change introduces a diagnostic in an
existing testcase where previously there was none:
protocol P {
associatedtype T
}
struct S<A: P where A.T == S<A>> {}
While it looks like this generic signature was built
correctly, in fact I think we weren't computing
conformances for the substitution of 'A' in 'S<A>'.
After trying small variations on the above testcase,
I quickly ran into SILGen crashes, which the diagnostic
now prevents. A few interesting cases still crash.
See test/decl/protocol/req/recursion.swift for the
gory details.

Sema: Use FoldingSetNode for ProtocolType
There was a weirdness with ProtocolType::get() that was causing me grief while trying to refactor getDeclaredType() and related code in another patch. Instead of caching the result like we do elsewhere, this would directly store the new type into the ProtocolDecl. This is smelly, so let's not do that. |

Sema: Improve a circularity-breaking hack
The old check was problematic because it would sometimes return ErrorType from accessing the generic parameters of a type that was in the process of having its generic signature validated. Instead fix the root cause of the circularity, which was recursion through resolveType() when resolving a type's inheritance clause. To fix it, let's just not walk adopted protocols when looking up the superclass of a class. Inheriting from an associated type does not seem very useful, and will probably be hard to get right in the general case. I wasn't able to reduce a useful test case, but this patch prevents compiler_crashers regressions with some other changes I'm working on. |
