fd2bf74f06 Move getCanonicalType from being a method on ASTContext to being a method on Type.

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.

ffb93e65b7 Fix a pretty big issue in typechecking. We were processing things like: 
func f() {
   var x = 4
   f()
}

as:
   var x = (4 f())
not:
   var x = 4; f()

5e44da89af Change how integer literals get types. Instead of having TypeChecker force them to __builtin_int32_ty, have sema give them integer_literal_type, and expect the library to define what that actually is for a given file.

6ab4eec127 Two changes that got mixed up: 
#1: Change type conversion errors to print the types involved, making the diagnostic better.  We still don't have ranges, but it is progress.

#2: Reimplement support for anonymous closure arguments (e.g. func($0+$1)) where func takes a closure, step #1.
 - This removes AnonDecl, replacing it with AnonClosureArgExpr.  $0 and friends have to be expressions since they don't get a type and don't get resolved until TypeChecking.
 - For now we just replace the existing broken support, a future step is to implement type checking support for them.

db236941d0 Check in a massive rewrite of how sema works for expressions in an effort to make way for separate parsing, name binding, type checking phases. 
Highlights of this include:
1) most of SemaExpr is gone now, when parsing, all expressions are assigned null types.
2) the introduction of a new TypeChecking pass, which assigns types to expressions, and checks their constraints.
3) ElementRefDecl now properly stores an access path for what it is accessing, and ElementRefDecl's get added to the AST.
4) The parser is much much simpler for expressions now, it just collects lists of primary exprs into SequenceExprs unconditionally.
5) This means that formation of binary expressions, function application etc is now done by TypeChecking.  This is actually simpler, though admittedly surprising.
6) This introduces a new -parse-dump mode which just parses but does not perform name binding or type checking.

I've been working on this for a while and it is still quite broken: it still doesn't handle anondecls at all, doesn't perform conversion checking for default tuple elements, has missing pieces of varname name binding etc.  However, there is no reason to not crash land it now, it's not like I'm going to break anyone else.

80e1ae6104 Rework a bunch of stuff in the type system: now the *only* way to name a type is through a 'typealias' and there is no such thing as a OneOfDecl. Instead, we have OneOfType's, which are always anonymous. "oneof declarations" and "struct declarations" are now both just sugar. 
This eliminates the NamedTypeDecl class (because there is now only one named type decl), eliminates OneOfDecl, renames AliasTypeDecl to NameAliasTypeDecl for good measure, and introduces OneOfType.

This preserves all existing syntax, and allows stuff like this:

func test6(checkboxenabled : oneof { Yep, Nope }) {
  test6(:Yep)
}

Which is an anonymous oneof.
