3176 scalar floating point, so that IEEE 128-bit floating point that
3177 can go in vector registers bind with vectors and not FP.

3200 have the Altivec ABI.
3201 (rs6000_init_builtins): Don't make TFmode use either IFmode or
3202 KFmode floating point nodes. Instead, have three separate nodes.
3203 (rs6000_scalar_mode_supported_p): Add support for IFmode to allow
3204 eventually moving the long double default to IEEE 128-bit floating
3206 (rs6000_opt_masks): Add -mfloat128.
3207 (struct rs6000_opt_var): Fix typo in comment.
3208 (init_cumulative_args): Initialize libcall field in
