aeeda4ee12 Parser: Parse operator decls. 
At the top level, if 'operator' is followed by 'infix', 'prefix', or 'postfix', consider it a contextual keyword, and parse an operator decl following it that looks like:

  operator {infix|postfix|prefix} <+> {
    attributes…
  }

Prefix and postfix operator decls currently admit no attributes. Infix operators have 'associativity {left|right|none}' and 'precedence <int>' attributes.

This patch implements parsing for operator declarations but does not yet attach the declared attributes to func decls for the operators.

e5b4b924a1 More work on constructors. Basic testcases with "constructor" declarations appear to be working, although there's probably more work to be done. (Both old-style and new-style constructors work for the moment.)

75907029f1 Add parsing and semantic analysis for a basic ConstructorDecl. Still missing: no IRGen, and semantic analysis to actually call them.

77fa49ec2b Introduce StructDecl and StructType; use them for structs instead of OneOfDecl/OneOfType. To keep this patch small, I'm leaving in LookThroughOneOf etc. for the moment, but that's next on the agenda.

4ca443d0f5 Add OneOfDecl; use it as a DeclContext for OneOfElementDecls instead of OneOfType, and get rid of the implicit TypeAliasDecl. Add TypeDecl as a base class for OneOfDecl and TypeAliasDecl (and StructDecl, once we have it). Adjust a whole bunch of stuff to this new scheme.

allow type coercion to influence overload resolution.

d5e7784010 Get rid of isModuleScope bit, since we don't like scattering bits across the AST; as a replacement, introduce TopLevelCodeDecl, which provides a DeclContext for all expressions and statements at the top level. <rdar://problem/11259941>.

94244131f7 Remove ElementRefDecl and DeclVarName. Add the replacement, PatternBindingDecl. Use proper pattern parsing for variable declarations. Uniformly use PatternBindingDecl for variable initialization. Adapt type-checking and IRGen for this new style of variable declaration. <rdar://problem/11124980>.

ce7780af04 I don't think we're really getting anything out of ArgDecl 
at the moment.  We can put it back if I'm wrong.

e22a30a130 revert r995: "introduce MetaTypeDecl (though nothing creates it yet)". 
After some pondering on this, I can just use DeclRefExpr(TypeAliasDecl) to
represent a named metatype, there is not need to have yet-another decl.  I'm
glad about this, because it didn't seem right.
