Add support for param for-loops over enum ranges

[reviewed by @vasslitvinov]

This adds support for param for loops over literal ranges whose bounds are defined by enum values and adds a few tests for the feature. The approach taken is very similar to the one taken for param for loops over integers, yet rather than counting through integers when stamping out the loop bodies, it iterates through the enumeration type.
