Description Kimmo Kinnunen 2021-01-05 04:01:36 PST 
WebKit IPC message names should indicate if the message is synchronous

Currently IPC message can be either synchronous or asynchronous but not both.
There should be an efficient way to check this based on the message name.
Checking this is important, because the dispatch functions for sync vs async messages on the receive side have different signatures.

This is needed because in WebGL GPUP "IPC stream" mode, the messages do not encode the message status byte for simplicity of operation.
