LibJS: Join locals, constants and registers into single vector

Browse source 
Merging registers, constants and locals into single vector means:
- Better data locality
- No need to check type in Interpreter::get() and Interpreter::set()
  which are very hot functions

Performance improvement is visible in almost all Octane and Kraken
tests.
