Refactor the way we optimize and remove on compile

[zazoomauro]

Instead of:

// optimize
if (this._compilerPass[PassConfig.TYPE_OPTIMIZE].length > 0) {
  this._processCompilerPass(PassConfig.TYPE_OPTIMIZE)
} else {
  for (let [id, definition] of this._definitions) {
    if (!this._container.get(id) && !definition.lazy) {
      let instance = this._getInstanceFromDefinition(definition)
      this._container.set(id, instance)
    }
  }
  this._frozen = true
}

// remove
if (this._compilerPass[PassConfig.TYPE_REMOVE].length > 0) {
  this._processCompilerPass(PassConfig.TYPE_REMOVE)
} else {
  for (let [id, definition] of this._definitions) {
    if (definition.public === false) {
      this._container.delete(id)
    }
  }
}

add this code to default proper compiler pass class and add it by default in to the compiler.
So create

• CompilerPass/OptimizePass
• CompilerPass/RemovePass
