bootstrap: initialize per-isolate properties of bindings separately
Browse files Browse the repository at this point in the history 
This patch moves the initialization of per-isolate properties of
the bindings that are in the embedded snapshot separate from the
initialization of their per-context properties. This is necessary
for workers to share the isolate snapshot with the main thread
and deserialize these properties instead of creating them from
scratch.
