Emit loop initializer for repeat arrays

This commit changes how arrays of repeating elements, e.g. [5; 12] are
compiled. Rather than create a constructor which explicitly initializes
each element to the given value (which causes compiler OOM for large
arrays), we emit instructions to allocate the array then initialize the
elements in a loop.

However, we can only take this approach outside of const contexts -
const arrays must still use the old approach.
