Detailed Description

A node (context) in the loaded contextual profile, suitable for mutation during IPO passes.

We generally expect a fraction of counters and callsites to be populated. We continue to model counters as vectors, but callsites are modeled as a map of a map. The expectation is that, typically, there is a small number of indirect targets (usually, 1 for direct calls); but potentially a large number of callsites, and, as inlining progresses, the callsite count of a caller will grow.
