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.

unsigned ranges/progressions.
The tests pass in JVM_IR for signed, but fail for unsigned due to
inlining being broken. We can disable the JVM_IR tests for unsigned,
while keeping them enabled for signed, to get better test coverage in
the interim until inlining is fixed.
We get the info for the underlying progression and invert it. For
progressions whose last bound was open (e.g., `until` loop), the
reversed version will have an open first bound and so the induction
variable must be incremented first.
Also unified the way of extracting HeaderInfo out of changed calls
(e.g., `indices.reversed()`), and fixed declaration parents in
ForLoopsLowering.
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.
Original problem is that lowered ir closures doesn't meet inliner expectations
about captured variable position in inlining method.
E.g.: Call 'foo(valueParam) { capturedParam }' to
inline function 'foo' with declaration
inline fun foo(valueParam: Foo, inlineParamWithCaptured: Bar.() ->) ....
is reorganized through inlining to equivalent call foo(valueParam, capturedParam1, cp2 ...).
But lowered closure for lambda parameter has totally different parameters order:
fun loweredLambda$x(extensionReceiver, captured1, cp2..., valueParam1, vp2...)
So before inlining lowered closure should be transformed to
fun loweredLambda$x(extensionReceiver, valueParam1, vp2..., captured1, cp2..)
