No, it isn't.  The metric is "time".  There is, fortunately, a
widely accepted standard for this metric.

The user doesn't care about inlining, limits or otherwise.
The user cares about the end results.

If tree-ssa has a side effect that causes some internal widget
to change that affects one of the external visible metrics of
"compile time" or "run time", then that's what we have to deal with.

Yes, the internal widget that changed makes it more difficult
for us to analyze what went wrong, or what needs changing, or
that the bottlenecks are.  But that's just too bad.
