These patches fix the tests in the testsuite that check whether -mno-float128
works properly.  In these cases, I explicitly run them with long double being
set to IBM extended double.

I have tested these on a little endian power8 system using two builds with long
double being set to IEEE and IBM 128-bit floating point.  These tests now pass
when long double is set to IEEE 128-bit floating point.  Can I check these into
the trunk and back port them to GCC 8.x?

	* gcc.target/powerpc/float128-3.c: Change tests that test for
	errors in enabling/disable IEEE 128-bit floating point use the
	-mabi=ibmlongdouble to force long double to be IBM extended.
	* gcc.target/powerpc/float128-5.c: Likewise.
	* gcc.target/powerpc/float128-mix.c: Likewise.
