Reland of https://chromium-review.googlesource.com/c/543042/. Now the OSR phase is only used when OSRing from the ast graph builder. When OSRing from Turbofan, the implementation is now in the graph building phase, at the beginning of the VisitBytecode function. We are no longer generating any OSRLoopEntry or OSRNormalEntry nodes, nor nodes for the possible code of the OSRed function which is before the OSRed loops. The trimming and reducing of the OSR phase is not done either. This change in the way the way the OSR is done enabled to remove the workaround to the bug mentioned below.
