Andreas Kling 640d48255b LibJS: Remove unhelpful environment lookup optimization for globals 
This optimization was no longer helpful after the bug fix for missing
invalidation on global delete was introduced in 331f6a9e6, since we
now have to check bindings for presence in the global environment every
time anyway.

Since the bytecode VM now has fast GetGlobal in most cases, let's not
even worry about this and just remove the unhelpful "optimization".

In fact, removing this is actually an *optimization*, since we avoid
a redundant has_binding() check on every global variable access. :^)
