* Fix and simplify TranslatorCache * Fix some assignment alignments, remove some unused usings * Changes to ILEmitter, separate it from ILEmitterCtx * Rename ILEmitter to ILMethodBuilder * Rename LdrLit and *_Fix opcodes * Revert TranslatorCache impl to the more performant one, fix a few issues with it * Allow EmitOpCode to be called even after everything has been emitted * Make Emit and AdvanceOpCode private, simplify it a bit now that it starts emiting from the entry point * Remove unneeded temp use * Add missing exit call on TestExclusive * Use better hash * Implement the == and != operators
