Some edges are self looping because of incorrect `horizontalPos`. This is occuring because of an unexpected scenario caused due to incorrect calculation of `inputApproch` and `outputApproach`. And all of this is occuring because of insufficient distance between two nodes. An example of the problem is shown in the image: https://imgur.com/aAmnzaK.

Following up on https://crrev.com/c/3540145, this also changes local debug evaluate scripts to be marked as shared-cross-origin. Drive-by-fix: This also updates the test for global debug evaluate to use the official (debug) API instead of peaking into the V8 internals unnecessarily.

This reverts commit aaedd8b7. Changes in the reland: The inital problem was caused by nodes that were removed during SL because they are no-ops but have an effect on typing (in the repro, this was e.g. PlainPrimitiveToNumber). The reland introdocues a new operator SLVerifierHint that is used exclusively in SL to provide hints to the verifier and that solves this problem. SLVerifierHint also replaces the previous use of TypeGuard to type constant nodes for the verifier.

This is a reland of 6b690a6b. The previous version of this CL was a bit too aggressive in the duplication of branch conditions. This caused an increase in register pressure in some cases, thus reducing performance. In fact, duplicating branch conditions that require an "== 0" to be added provides no benefits. We are thus now a bit less aggressive, and only duplicate comparisons.

During a frame merge we call ForEachValue that "get"s every live register, including the virtual accumulator. That currently fails since we need to check if the register is the virtual accumulator and set/get the accumulator field in InterpreterFrameState. The virtual accumulator slot in RegisterFrameArray (the same as the return address in a live frame) is actually unused. So we can use this slot for the InterpreterFrameState's accumulator, instead of a separate field.
