using different register names.

Examples:

	ADC R24, R14, R12          <=>     adc x12, x14, x24
	ADDW R26->24, R21, R15     <=>     add w15, w21, w26, asr #24
	FCMPS F2, F3               <=>     fcmp s3, s2
	FCMPD F2, F3               <=>     fcmp d3, d2
	FCVTDH F2, F3              <=>     fcvt h3, d2

2. Go uses .P and .W suffixes to indicate post-increment and pre-increment.
