For calls of the form ident(...) record position of the identifier as the position of the call. For other calls record positions of the opening parenthesis.

This guarantees that for expressions of the form function(){}() call position will not intersect with positions recorded for function literal which is used by the debugger for scope chain resolution.

Loosen the requirement for Map equivalency on several map checks, including checks up the prototype chain, that are not sensitive to ElementsKinds. These selected map checks should also match against FAST_DOUBLE_ELEMENT and FAST_ELEMENT transitions of the original map. This specifically helps all variants of transitioned JSArrays to still efficiently call builtins like push, pop and sort.

CPU-eating DOS attacks against node.js servers.  Based on code from

V8 themselves or those that do not use snapshots.  A snapshot-based
