[PATCH v2 05/14] perf report: mark inlined frames in output by " (inlined)" suffix

[Milian Wolff <milian.wolff@kdab.com>]

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.
