Production | Deploy preview

Profile showing before/after: https://share.firefox.dev/45Ogp1l

The previous implementation was recursing to check whether the parent stack matches the search filter. With some profiles I was seeing JS stack exhaustion exceptions, but only on localhost:4242 with the development environment, not in the production environment.

Nice! Looks good to me, thanks! Manually tested but I also assume we have tests for this already.

if (result === undefined) {
result = computeFuncMatchesFilter(func);
funcMatchesFilterCache.set(func, result);
const funcMatchesSearch = makeBitSet(funcTable.length);

wohoo another use case of bitsets!

// Set any stacks which don't include the search string to null.
// TODO: This includes stacks in markers; maybe we shouldn't clear marker stacks?

I don't know why but I'm used to this version where we filter the marker stacks too. But maybe that's surprising for people?
