03c737625a Make sure transitioned arrays efficiently call builtin Array functions
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.

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.
