This testcase fails with a syntax error, scan-assembler-not with
2 operands would need to have target or xfail as the second operand, not 1.
Removing the 1 doesn't work, because xsnabsqp instruction is actually
emitted. Given that the comments on the functions explicitly mention
that it expects one XSABSQP and one XSNABSQP instruction, I've changed
it to scan-assembler-times instead, tested on powerpc64le-linux and
committed as obvious to trunk.

* gcc.target/powerpc/float128-hw7.c: Use scan-assembler-times
instead of scan-assembler-not for xsnabsqp.
