HGlobalValueNumberingPhase::CollectSideEffectsOnPathsToDominatedBlock()
used to self-recurse before this commit, causing stack overflows on
systems with small stack sizes. Make it non-recursive by storing
intermediate results in a heap-allocated list.

The first commit is the obvious way to implement it, the second commit optimizes a bit.

Switching to heap allocations might in theory have performance implications but, as a data point, it doesn't seem to affect the running time of the node.js test suite.

I don't expect any performance impact because this part of Crankshaft should run on the background thread anyways.

You probably can use the list as a stack (instead of queue) and just pop the last element at the end of the loop? That would lessen the peak memory use.

Made the suggested change. I wasn't sure if walking them in a different order was sound but it computes the union so I suppose it must be.

LGTM.

FWIW 2nd commit didn't traverse the same order as the recursion did either (BFS vs DFS).

LGTM but is this a backport of a change in V8? or should this land upstream first?

V8 is not likely to ship a version with this patch anymore, and Crankshaft is being deprecated, so I'm not sure how much value upstreaming has. I would give lgtm if @bnoordhuis provides a CL for upstream though.

I'm fine with floating it as a patch. Upstreaming it would be make-work for the both of us.
