1052723 - Add telemetry for more GC phases

Status: NEW

(Core :: JavaScript: GC, defect)

Description

[Terrence Cole [:terrence]]

We only have phases right now for aggregate marking and sweeping. This makes it hard to tell whether our long tail of long-max-pause GC's might be caused by some particular phase exploding commonly, or by general slowness. This also means we don't have any good way to try to correlate regressions in our aggregate stats.

I assume you meant to assign this to yourself Steve.

That's what happens when I attempt to use the bugzilla interface directly instead of going through bzexport...
