If we encounter an error prior to 'initialize-static-globals', this pass will not run, and will not convert globals to be statically-initialized at all, regardless of whether or not it would have been possible. This means that diagnostics on failure to do so would then always be emitted, likely as false-positives. Avoid emitting these diagnostics in a context that contains a prior error. As a future alternative, we could refine the conditions that make `initialize-static-globals` give up on a given function/value, but for now we need to ensure we do not emit spurious diagnostics.
