Aligned vector spills and variably sized stack frames
...ealignment. This seems like it might be
useful in other context as well, but I can't name any at the moment.
One thing that occurs to me is that many spills are down rare paths.
Maybe it would make sense to only do dynamic alignment for hot
spill/reloads? We could then simply override the heustic to always use
unaligned spills.
I don't really have a sense for how hard (3) would be to implement.
Anyone have an intuition?
