wast-identifer-to-index transformation

Transforms some WAST semantics into WAT or WASM (actually specs semantics).

WAST allows you some handy shortcuts, like providing the identifier of a local instead of its index.

Example (refering to a param)

In

(func (param $name i32)
 (get_local $name)
)

Out

(func (param i32)
 (get_local 0)
)

Example (refering to a func)

In

(func $name)
(func
 (call $name)
)

Out

;; first function in moduleinst.funcaddrs (index 0)
(func $name)

(func
 (call 0)
)
