Summary: To make this work for both AFGR64 and FGR64 register sets, I've had to make the instruction definition consistent with the white lie (that it reads the lower 32-bits of the register) when they are generated by expandBuildPairF64(). Corrected the definition of hasMips32r2() and hasMips64r2() to include MIPS32r6 and MIPS64r6.
