rs6000: xfail float128 comparison test case that fails on powerpc64.
This patch xfails a float128 comparison test case on powerpc64 that
fails due to a longstanding issue with floating-point compares.
See PR58684 for more information.
When float128 hardware is enabled (-mfloat128-hardware), xscmpuqp is
generated for comparison which is unexpected. When float128 software
emulation is enabled (-mno-float128-hardware), we still have to xfail
the hardware version (__lekf2_hw) which finally generates xscmpuqp.
