* config/rs6000/float128-sed: New files to convert TF names to KF
names for PowerPC IEEE 128-bit floating point support.
* config/rs6000/float128-sed-hw: Likewise.
* config/rs6000/float128-hw.c: New file for ISA 3.0 IEEE 128-bit
floating point hardware support.
* config/rs6000/float128-ifunc.c: New file to pick either IEEE
128-bit floating point software emulation or use ISA 3.0 hardware
support if it is available.
* config/rs6000/quad-float128.h: New file to support IEEE 128-bit
floating point.
* config/rs6000/extendkftf2-sw.c: New file, convert IEEE 128-bit
floating point to IBM extended double.
* config/rs6000/trunctfkf2-sw.c: New file, convert IBM extended
double to IEEE 128-bit floating point.
* config/rs6000/t-float128: New Makefile fragments to enable
building __float128 emulation support.
* config/rs6000/t-float128-hw: Likewise.
* config/rs6000/sfp-exceptions.c: New file to provide exception
support for IEEE 128-bit floating point.

VSX code, enable IEEE 128-bit floating point. If the compiler can
compile IEEE 128-bit floating point code with ISA 3.0 IEEE 128-bit
floating point hardware instructions and it supports declaring
functions with the ifunc attribute, enable ifunc functions to
switch between software and hardware support.
