Added creation and initialization of the test module and its dependencies.
When looking at the emptyProgression test,
I found that getProgressionLastElement was not found,
which should be resolved from the dependencies.
Library methods such as 'listOf' are resolved
to have the package fragments as their parents,
but JVM expects their containing file classes as parents.
This fix generates those file classes and
uses them as parent replacements for such library methods.
last-exclusive progressions (i.e., "until" progressions and loop over
array indices).
This change makes it possible to correctly implement the handling of
"step" progressions. Computing the last element of a stepped progression
requires that the last is inclusive.
Also invert the while loop (into if + do-while) that is used when
lowering for-loops over progressions that cannot overflow. This keeps
the performance characteristics closer to the ForLoopsLowering in
kotlin-native, since the goal is to converge to this shared version.
Also used IrType instead of KotlinType, where possible.

HeaderInfo object, and modifying the operator in the loop condition.
The "additional emptiness condition" is no longer necessary with this.
The open/closed property was removed from HeaderInfo in an earlier
commit, but bringing it back in to simplify the loop building makes
more sense.
Also expanded tests for evaluation order of range bounds.
