Power10: Add missing IEEE 128-bit XSCMP* built-in mappings.

Browse Source 
This patch adds support for mapping the scalar_cmp_exp_qp_* built-in functions
to handle arguments that are either TFmode or KFmode, depending on whether long
double uses the IEEE 128-bit representation (TFmode) or the IBM 128-bit
representation (KFmode).  This shows up in the float128-cmp2-runnable.c test
when long double uses the IEEE 128-bit representation.
