Jonne Ransijn c1acf77d6b LibJS: Add HashMap for finding Bindings by name ...

`find_binding_and_index` was doing a linear search, and while most
environments are small, websites using JavaScript bundlers can have
functions with very large environments, like youtube.com, which has
environments with over 13K bindings, causing environment lookups to
take a noticeable amount of time, showing up high while profiling.

Adding a HashMap significantly increases performance on such websites.
