BR 3392539: some errors can "cascade". Allow suppressing if dead.

In BR 3392539, the error:

helloW.s:18: error: label `rurt' changed during code generation
[-w+error=label-redef-late]

... occurs a number of times after we have already issued an
error. This is because the erroring instruction computes to a
different size during code generation; this causes each subsequent
label to cause a phase error.

The phase error simply doesn't make much sense to report: if we are
already committed to erroring out, it is more likely an error cascade
rather than an error in its own right, so just suppress it in that
case.
