Highlights:
- Record all imports and exports in the ModuleDescriptor.
- Remove ImportDeclaration; instead, introduce a new variable kind for imports.
- Set name on default exported anonymous functions.
Still to do: declaration of namespace imports.

This replaces the vtable on AstNode with a NodeType tag. The visitors replace double dispatch with a single switch over the NodeType.
For now, visitors with subclasses still have virtual methods themselves. We should probably specialize them later as well.
The uint8_t NodeType allows us to better pack memory, saving 8-16 bytes on many AST nodes (with additional packing that I'll do in a follow-up CL)

1) Validation fails for literal indexes too large for accessing a given
heap type
2) Removes the special handling of FloatishDoubleQ, and FloatQDoubleQ;
the inheritance issue that required this special handling was fixed in
another CL.
3) Fix a macro name (from asm_* to ASM_*)
