Remove the default contains_call parameter on location summaries.

Remove the default contains_call parameter on location summaries.

The plan is to use this parameter to make finer distinctions between
calls (e.g., safepoint vs. non-safepoint).  It's a bit safer to eliminate
the default.

I moved this here because the name is shorter at the call sites :)

I have a different plan for this so please do not pass temp registers just yet.
We will invoke that solution (temp registers) if the others do not work.
