Before this commit, one could either capture all stack frames (by passing
maxFrameCount = 0) or a maximum of N frames (by passing maxFrameCount = N). This
commit introduces the ability to capture the first frame (by default ignoring
self hosted frames) with some target principals. This new option required
replacing the `unsigned maxFrameCount` parameter with the introduction of a new
sum type to describe the stack capturing behavior:
StackCapture = AllFrames
| MaxFrames(unsigned n)
| FirstSubsumedFrame(JSPrincipals* p, bool ignoreSelfHosted)
This is obviously more wordy in C++ than we'd like, but does make the stack
capturing more explicit rather than relying on the sentinal 0 to stand in for
infinity.
