Unlike signed integers, a larger unsigned type does not mean a lower
minimum value, so `x - 1` can overflow even if `x` is casted to a larger
type.
#KT-42186 Fixed
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.
