Austin Clements caf9e15fb7 runtime: drop stack-allocated pcvalueCaches
Now that pcvalue keeps its cache on the M, we can drop all of the
stack-allocated pcvalueCaches and stop carefully passing them around
between lots of operations. This significantly simplifies a fair
amount of code and makes several structures smaller.

This series of changes has no statistically significant effect on any
runtime Stack benchmarks.

I also experimented with making the cache larger, now that the impact
is limited to the M struct, but wasn't able to measure any
improvements.

This is a re-roll of CL 515277
