Some parses are actually re-parses of an already parsed function; things
like source position collection, CallPrinter AST walks, debugger, etc.

These may want slightly different parse behaviour -- in particular, we
likely don't want to post parallel compile tasks for them. So, keep
track externally of which parses are reparses, and suppress parallel
compile tasks for them.
