## This testcase shows how `c.j`, `c.jal` and `jal` can be relaxed to `qc.e.j` and `qc.e.jal`
## with Xqcilb, when the branches are out of range, but also that these can be compressed
## when referencing close labels.
## The only problem we have here is when `jal` references an out-of-range label, and `rd` is
## not `x0` or `x1` - for which we have no equivalent sequence, so we just fail to relax, and
## emit a fixup-value-out-of-range error.
