  [LegacyPM] Call getPassName only when needed

Even when time tracing is disabled, getPassName is currently still
called. This adds an avoidable virtual function call for each pass.
Fetching the pass name only when required slightly improves
compile-time (particularly when LLVM is built without LTO).
