I think __divtf3 must remain as it is now, or we break the C ABI.

When I originally implemented this stuff I proposed using the HPUX
function names for __float128 operations (_U_Qf* -- see
ia64_hpux_init_libfuncs) but it was considered to be moot as long as
we didn't actually have an 128bit floating point library.  Has that
changed?
