v0.12: Poor choice of V8 version

[jakobkummerow]

I just happened to notice that node v0.12 ships V8 3.28.73. That's a pretty bad choice, as 3.28.73 was just a random trunk snapshot that was briefly considered as the basis for the 3.28 branch, but was then discarded/abandoned because it was too unstable. The tip of the branch is 3.28.71.19: https://chromium.googlesource.com/v8/v8.git/+/branch-heads/3.28

While the 3.28 branch is generally outdated and hence unmaintained anyway, at least using its tip is very strongly preferable over using a random trunk commit from shortly after the branch point. To be very clear: There are known crash and security bugs in 3.28.73 that are fixed in 3.28.71.19!

#9185?

Ah. Well, I would recommend to ship that ASAP.
