PowerPC: Use __float128 instead of __ieee128 in tests.

PowerPC: Use __float128 instead of __ieee128 in tests.

I have split all of these patches into separate patches to hopefully get them
into the tree.

Two of the tests used the __ieee128 keyword instead of __float128.  This
patch changes those cases to use the official keyword.

I have tested this patch with bootstrap builds on a little endian power9 system
running Linux.  With the other patches, I have built two full bootstrap builds
using this patch and the patches after this patch.  One build used the current
default for long double (IBM extended double) and the other build switched the
default to IEEE 128-bit.  I used the Advance Toolchain AT 14.0 compiler as the
library used by this compiler.  There are no regressions between the tests.
There are 3 fortran benchmarks (ieee/large_2.f90, default_format_2.f90, and
default_format_denormal_2.f90) that now pass.

Can I install this into the trunk?

We have gotten some requests to back port these changes to GCC 10.x.  At the
moment, I am not planning to do the back port, but I may need to in the future.
