5d8a7ff9e7 Allow multiple comma-separated enum elements in a 'case' decl. 
Introduce an EnumCaseDecl for source fidelity to track the 'case' location and ordering of EnumElementDecls. Parse a comma-separated list of EnumElementDecls after a 'case' token.

e109124186 Replace 'union' keyword with 'enum'. 
This only touches the compiler and tests. Doc updates to follow.

3cc01cf7d6 Introduce AbstractFunctionDecl -- a base class for ConstructorDecl, 
DestructorDecl, FuncDecl -- and move some of the common concepts and logic
into it

No functionality change.

dae1d10c76 Fix an error in DeclNodes: ValueDecl did not include DestructorDecl

1ddb34fb71 Factor generic parameters and associated types into their own decl nodes. 
Previously, TypeAliasDecl was used for typealiases, generic
parameters, and assocaited types, which is hideous and the source of
much confusion. Factor the latter two out into their own decl nodes,
with a common abstract base for "type parameters", and push these
nodes throughout the frontend.

No real functionality change, but this is a step toward uniquing
polymorphic types, among other things.

674a03b085 Replace "oneof" with "union"...everywhere. 
We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!

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.)

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.

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.
