Description
On various architectures there exist registers that require different encoding characteristics. For example, on x64 there are additional registers available (R8-R15 and XMM8-XMM15), which require the use of the REX prefix (or a VEX-encoded instruction).
Given that these change how the instruction is encoded, it would be beneficial if there was a stress-mode that would prefer these registers in order to help validate that the emitter has them properly handled.
