Daniel Sanders bb8824f19f Re-commit with some instrumentation: [globalisel][tablegen] Support zero-instruction emission. ... Summary: Support the case where an operand of a pattern is also the whole of the result pattern. In this case the original result and all its uses must be replaced by the operand. However, register class restrictions can require a COPY. This patch handles both cases by always emitting the copy and leaving it for the register allocator to optimize. The previous commit failed on the windows bots and this one is likely to fail on those same bots. However, the added instrumentation should reveal a particular isHigherPriorityThan() evaluation which I'm expecting to expose that these machines are weighing priority of two rules differently from the non-windows machines.
