Anonymous d1cc67bbe1 LibJS: Avoid unnecessary ToObject conversion when resolving references
When performing GetValue on a primitive type we do not need to perform
the ToObject conversion as it will resolve to a property on the
prototype object.

To avoid this we skip the initial ToObject conversion on the base value
as it only serves to get the primitive's boxed prototype. We further
specialize on PrimitiveString in order to get efficient behaviour
behaviour for the direct properties.

Depending on the tests anywhere from 20 to 60%, with significant loop
overhead.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:
