[turbofan] Add effects to StringAt operators Add effect input and output to String.p.char[Code]At/codePointAt. This is necessary to fix an hard to reproduce bug, a repro for which is included. However, the only way to get the repro included in this CL to fail is to run it with the patch of 873382: [turbofan] Speculate on bounds checks for String#char[Code]At but WITHOUT this patch. This fixes a scheduling problem triggered by 873382 that caused a bounds check to get scheduled after the associated access.
