This was found using clippy with `-D clippy::perf`. Since we know the size of the
slice at compile time, we can avoid heap allocating a Vec.

This tweaks `parse_content()` logic in order to reduce the amount
of vector growing, as the final vector capacity is already known
beforehand.

In the event that a for loop iterates over `Value`s and also referes to
elements not defined by the for loop, `find_value_in_for_loop` would needlessly
call `ForLoop::get_current_value` for each of those lookups.

`ForLoop::get_current_value` can be expensive, potentially incurring a clone of
a possibly large `Value`.

This change moves the `get_current_value` so that we only clone a `Value` when
needed.
