Leszek Swirski a66c7a38fa [compiler] Create ParseInfo on BG thread ... Rather than creating a ParseInfo when creating a BackgroundCompileTask (and passing ownership across to the BG thread which deallocates it), create one when running it. This allows the ParseInfo Zone to be both allocated and deallocated on the same thread, which will improve its allocator friendliness. As a side-effect, we now use the on-heap PreparseData from the SharedFunctionInfo, rather than cloning the in-Zone PreparseData. This means that we don't have to copy the PreparseData across Zones, but we do need to Unpark the LocalHeap when accessing preparse data.
