compiler_rt: Tracking Issue PPC Routines

[matu3ba]

As far as I know, there is no specification and the "libgcc code is the specification".

Fromlibgcc/config/rs6000/float128-ifunc.c and those looks to be the complete list judging from what we already have in compiler_rt (without math routines):

• [ ] TFtype __addkf3 (TFtype, TFtype)
• [ ] TFtype __subkf3 (TFtype, TFtype)
• [ ] TFtype __mulkf3 (TFtype, TFtype)
• [ ] TFtype __divkf3 (TFtype, TFtype)
• [ ] TFtype __negkf2 (TFtype)
• [ ] TFtype __powikf2 (TFtype, SItype_ppc)
• [ ] CMPtype __eqkf2 (TFtype, TFtype)
• [ ] CMPtype __nekf2 (TFtype, TFtype)

• [ ] CMPtype __unordkf2 (TFtype, TFtype)
• [ ] TFtype __extendsfkf2 (float)
• [ ] TFtype __extenddfkf2 (double)
• [ ] float __trunckfsf2 (TFtype)
