2711ad03c9 now that WalkOrder is in a common header, move the WalkStmt to be a 
Stmt method, rename it to just 'walk' to follow the naming convention,
and give it an accurate doc comment for good measure.

cb59d9c926 split the walkorder enum out to its own header file. This is a silly waste of 
a file, but is needed to share it between two other heads.  Header files seem
so baroque.

a8e2788184 implement semantic analysis for FuncExpr and have the parser lower func decls 
to func exprs.  All the tests pass again.  Now we have a strict equality 
between:

  func foo(a : int) -> int { a+1 }

and 

  var foo = func(a : int) -> int { a+1 }

except we don't support the later syntax yet.  We also really need return, though
we're getting closer to being able to usefully support it.

63ce0be641 make the big switch: {} are now statements, not expressions. This removes some 
annoying things from the grammar (like expr-non-brace), and makes it so that 
the body/else of an if is just a statement.

This patch has a fairly serious caveat that we just drop function bodies on the
floor now, since we have no "stmtexpr" sort of thing to represent the syntactic
sugar that is func.  We'll fix that soon.

096a3e16bc switch to range-based for loops where possible. I'm actually surprised how many 
places are blocked by needing an index exposed for other purposes.  Not having a
MutableArrayRef doesn't help either.

6720390c84 Implement a first, very simple cut at ranking conversions for overload sets. This is important because we previously required exact type matching for overload resolution, and (int) != (.x : int) so no arguments with names would match up with anonymous values. 
We still don't use ranking for binary operators etc.

3b4a8b03d2 1. With overloading in play, SemaDecl should never resolve unqualified lookup that hits at translation unit scope to a DeclRefExpr. Doing so can break overloading. 
2. This exposed a bug: when parsing structs, we weren't adding all decls to the translation unit, we were just adding the type alias.
3. This exposed that TypeChecking wasn't handling OneOfElementDecl.
4. Introduce a new NLKind enum in NameLookup instead of passing around a bool.
5. Have unqualified lookup that returns an overload set form a new OverloadSetRefExpr, which has dependent type.
6. Enhance various stuff to handle OverloadSetRefExpr.  It's still not fully handled yet though, so it can't be used for anything useful.
7. Change Expr.cpp to print types with << instead of T->print(OS) which is simpler and correct in the face of null.

5e28a6fcdd Finally get around to doing a major type system refactoring, where we introduce Type as a "smart pointer" and rename the existing Type class to TypeBase. 
This prevents use of isa/dyn_cast/etc on Type*'s and means we just pass around Type by value instead of having to use Type* everywhere.

7530ec988c Add a error to reject foo() when foo is not a function type. Previously we allowed it because these are two valid top-level values, but we now reject them because they are almost certainly a bug. This can be disabled by putting a space between them if this is useful for some reason.

aeb7c0895e The isGroupingParen() predicate doesn't make sense since TupleExpr can be used to create tuple expressions out of a scalar when there is a single element involved. In this case, isGroupingParen would return true but the source and dest types would be different. 
This didn't manifest as a bug yet, but it doesn't make sense to wait until it does.  This aspect of grouping parens is a syntactic issue, so make the creator of TupleExpr specify whether the expr is a grouping paren or not and persist this.

not:
   var x = 4; f()
