Warnings about the comparison of const and non-const objects can be fixed by making the comparison operator function const. mfbt/tests/TestDoublyLinkedList.cpp:158:36 [-Wambiguous-reversed-operator] ISO C++20 considers use of overloaded operator '==' (with operand types 'SomeClass' and 'SomeClass') to be ambiguous despite there being a unique best viable function mfbt/tests/TestDoublyLinkedList.cpp:159:38 [-Wambiguous-reversed-operator] ISO C++20 considers use of overloaded operator '==' (with operand types 'SomeClass' and 'SomeClass') to be ambiguous despite there being a unique best viable function Depends on D179022 Differential Revision: https://phabricator.services.mozilla.com/D179023
