Aliaksandr Kalenik 3661d674ae LibJS: Add optimized GetGlobal instruction to access global variables ...

Using a special instruction to access global variables allows skipping
the environment chain traversal for them and going directly to the
module/global environment. Currently, this instruction only caches the
offset for bindings that belong to the global object environment.
However, there is also an opportunity to cache the offset in the global
declarative record.

This change results in a 57% increase in speed for
imaging-gaussian-blur.js in Kraken.
