x86/Intel: accept mandated operand order for vcvt{,u}si2s{d,s}

x86/Intel: accept mandated operand order for vcvt{,u}si2s{d,s}

As pointed out before, the documentation mandates the rounding mode to
follow the GPR, so gas should accept such input. As the brojen code got
released already we sadly will need to continue to also accept the
badly ordered operands.
