    Reason for revert: Blocks V8 roll into Chromium (changed error messages cause tests to fail):

    Original change's description:
    > Improve error messages for property access on null/undefined
    >
    > Only print the property name when accessing null/undefined if we can
    > convert it to a string without causing side effects.
    > If we can't, omit the property name in the error message.
    > This should avoid confusion when the key is an object with toString().
    > E.g. undefined[{toString:()=>'a'}] doesn't print 'read property [object
    > Object]' anymore, which was misleading since the property accessed would
    > be 'a', but we can't evaluate the key without side effects.
