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.

433d6de807 implement AST and parser support for 'return'. We're still not doing a conversion
to a return type yet though.  We happily diagnose thigns like this as an error:

func foo() -> int {
  return 4 5
}

350b89e6e4 Represent assignments as their own AssignStmt, preserving the model we had
before, but removing the hack where we'd represent them as a binary operator
with a null operator function.  We still have no clear semantics for what 
is valid or not.

to support and good for completeness.

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.

IntegerLiteral to IntegerLiteralExpr, which is good for consistency anyway.

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.

0b068577bd Use TupleShuffleExpr to finally eliminate the last remenants of the
ASDAG.  Our AST is actually a tree again.  The testcase compiles into:
...
          (vardecl 'c' type='(a : int, b : int)')
          (vardecl 'd' type='(b : int, a : int)'
            (tuple_shuffle type='(b : int, a : int)' Elements=[1, 0]
              (declref_expr type='(a : int, b : int)' decl=c))))))

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.
