Brian White 6a5ab5d550 fs: include more fs.stat*() optimizations
Including:

* Move async *stat() functions to FillStatsArray() now used by the
sync *stat() functions

* Avoid creating fs.Stats instances for implicit async/sync *stat()
calls used in various fs functions

* Store reference to Float64Array data on C++ side for easier/faster
access, instead of passing from JS to C++ on every async/sync *stat()
call
