Bug 1359000 (part 4) - De-inline profiler_call_{enter,exit}. r=mstange.

This possibly incurs an extra function call (depends on exactly how much inling
the compiler does). But it helps enormously with subsequent refactorings,
because PseudoStack (and related types) don't need to be visible in
GeckoProfiler.h, which is exported outside the profiler.
