Bug 1862 – asm: [ESI+1*EAX] should be a legal addr mode

Currently gives a 'bad addr mode' error, eg: asm { movapd XMM1, [ESI+1*EAX]; } It correctly accepts multipliers of 2, 4, 8, and 16, but a multiplier of 1 should be legal. The reason for wanting this is that it allows you to control which register is used for scaling. movapd XMM1, [ESI+EAX] can be encoded as either movapd XMM1, [1*ESI+EAX] or as movapd XMM1, [ESI+1*EAX] This makes a difference when you have a RAT stall caused by reading too many registers in a single clock cycle.

Fixed dmd 1.028 and 2.012
