This patch fixes a thinko that I had that prevented negation of __ibm128 values
if long double is IEEE 128-bit binary floating point.

I have checked this on a little endian power8 system with builds where the long
double is set to IEEE and IBM 128-bit binary floating point, and it fixes some
tests in the testsuite when long double is IEEE.  Can I install this on the
trunk and back port it to GCC 8.x?
