AssemblyScript IR

AssemblyScript does not maintain a statement or expression level IR.
However it has namespace / class / function level IR to handle generic and layered symbol resolving.

For each source file, it will be mapped to File in IR. It contains all sub element in this TS source file.

For json file, currently it will be treat as a special source file and generated a fake IR.

The namespace will be mapped to Namespace.

For each class / interface / function

• During initialization it will be mapped to prototype.
  
• When resolving it, a detail Class / Interface / Function will be created according to prototype.

For each method

• During initialization it will be mapped to unbound prototype.
  
• When resolving it, a bound prototype will be created (see FunctionPrototype.toBound).
  
• Then a detail Function will be created according to bound prototype.

The global variable will be mapped to Global.

The local variable and parameter will be mapped to Local.
