Nick Ripley f4494522dc runtime: use frame pointer unwinding for block and mutex profilers 
Use frame pointer unwinding, where supported, to collect call stacks for
the block, and mutex profilers. This method of collecting call stacks is
typically an order of magnitude faster than callers/tracebackPCs. The
marginal benefit for these profile types is likely small compared to
using frame pointer unwinding for the execution tracer. However, the
block profiler can have noticeable overhead unless the sampling rate is
very high. Additionally, using frame pointer unwinding in more places
helps ensure more testing/support, which benefits systems like the
execution tracer which rely on frame pointer unwinding to be practical
to use.
