[PATCH v2 05/14] perf report: mark inlined frames in output by " (inlined)" suffix
The original patch that introduced inline frame output in the various browsers used this suffix already. The new centralized approach that uses fake symbols for inlined frames was missing this approach so far. Instead of changing the symbol name itself, we only print the suffix where needed. This allows us to efficiently lookup the symbol for a given name without first having to append the suffix before the lookup.
