Subject: [PATCH] perf, utils: Print the original modifiers in event_name

From: Andi Kleen <ak@...ux.intel.com>

We need to save the original string for perf stat output,
otherwise :t and :c are invisible.

This used to work, but broke with the parser refactoring.

Not sure if this is the best fix.
