Aliaksandr Kalenik 42e9dfedc2 LibJS: Pre-calculate the number of bindings for function environments ...

We can use `ensure_capacity` for binding vectors if we know their sizes
in advance. This ensures that binding vectors aren't reallocated during
the `function_declaration_instantiation` execution.

With this change, `try_grow_capacity()` and `shrink_to_fit()` are no
longer visible in the `function_declaration_instantiation()` profiles
when running React-Redux-TodoMVC from Speedometer.
