Andreas Kling 620c495d31 LibJS: Skip lazy intrinsic allocation check for objects without them ...

Most JS::Objects don't have lazily-allocated intrinsic properties,
so let's avoid doing hash lookups by putting a flag on JS::Object that
tells us whether it's present in s_intrinsics.

Takes CPU time spent in those hash lookups from 1-2.5% to nothing on
various JS heavy pages.
