Josef Weidendorfer 39cea8c6da Callgrind: fix Ir cost update for ignored functions ...

Also without cache simulation, Callgrind maintains Ir cost.
This is done in setup_bbcc by incrementing an execution counter
for last_bbcc (the cost center for the previously executed BB
in current context) and the global cost counter.

However, we forgot to increment any counter if the currently
executing function should be ignored. We need to still update
costs, add attribute this to a not-ignored call site (as
given in CLG_(current_state).nonskipped).

Before this fix, there was a difference in Ir cost with vs. without
cache simulation. This was because ignored functions (e.g. PLT code)
contributed no cost when not doing cache simulation.
