[JVM+IR] Unify new debugger tests expectations

This commit unifies the expectation format between the stepping and
LVT tests in the new debugging test harness.

Furthermore, it introduces a compression of runs of locations without
linenumbers. These default to showing as bytecode offsets from
previous line number, which overspecifies the tests: the bytecodes
chosen should not be constrained by a debugging step test.
