[PATCH] During PHI elimination, split critical edges that move copies out of loops

[Quentin Colombet]

My concern was this:

>   it currently breaks a few tests


What do you mean by "break"?

>From your last comment, I believe we generate worse code.
If that the case, then just put a flag to preserve the previous behavior and file PR for the regression you find so that we can work on fixing them.
Other than that, the change itself looks good to me.

Thanks,
