Fix compilation of this macro under gcc-4.9 for MIPS32.
Some point after gcc-4.2 the MIPS inline assembly restrictions changed -
=h (hi register) disappeared from the list of restrictions and can no
longer be used.
So, until someone requires an assembly version of this function,
just use a non-assembly version and let the compiler sort it out.
