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.
