Andreas Kling ad7c1e147f LibJS: Add SetGlobal bytecode instruction for cached global writes ...

Before this change, setting a global would end up as SetLexicalBinding.
That instruction always failed to cache the access if the global was a
property of the global object.

1.14x speedup on Octane/earley-boyer.js
2.04x speedup on MicroBench/for-of.js

Note that MicroBench/for-of.js was more of a "set global" benchmark
before this. After this change, it's actually a for..of benchmark. :^)
