Description Jonathan Bedard 2022-09-16 10:14:35 PDT

Add the --signpost option to both run-webkit-tests and WebKitTestRunner. The idea behind this option is to provide contributors with tools to measure performance inside WebKitTestRunner to identify expensive portions of code, in particular sections which get more expensive as we scale processes on a machine.
