Trevor Norris	36e8a2c63d	node: improve performance of hrtime() process.hrtime() was performing too many operations in C++ that could be done faster in JS. Move those operations over by creating a length 4 Uint32Array and perform bitwise operations on the seconds so that it was unnecessary for the native API to do any object creation or set any fields. This has improved performance from ~350 ns/op to ~65 ns/op. Light benchmark included to demonstrate the performance change.

node: improve performance of hrtime()

process.hrtime() was performing too many operations in C++ that could be
done faster in JS. Move those operations over by creating a length 4
Uint32Array and perform bitwise operations on the seconds so that it was
unnecessary for the native API to do any object creation or set any
fields.

This has improved performance from ~350 ns/op to ~65 ns/op. Light
benchmark included to demonstrate the performance change.

fs: use pushValueToArray for readdir(Sync)

Improve performance by pushing directory entries to returned array in
batches of 8 using pushValueToArray() in JS. Add benchmarks to
demonstrate this improvement.
