<pre>--print-before/after take a list of passes. For example,
--print-before=globalopt. `llvm::shouldPrintBeforePass()` checks that the pass
name matches e.g. "globalopt". This works under the legacy PM. But in the new
PM, the pass instrumentation responsible for printing IR is given not the pass
name like "globalopt" but rather "GlobalOptPass", so it never matches. So
--print-before/after end up silently never working under the new PM.</pre>
