Split up generation of test data for codegen/box/ranges into signed and

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.
