Daniel Cederman 05452859f5 [Sparc] Select correct register class for FP register constraints
Summary: The fX version of floating-point registers only supports
single precision. We need to map the name to dX for doubles and qX
for long doubles if we want getRegForInlineAsmConstraint() to be
able to pick the correct register class.
