p8vector-fp.c: New test for floating point scalar operations when...

2013-10-03  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* gcc.target/powerpc/p8vector-fp.c: New test for floating point
	scalar operations when using -mupper-regs-sf and -mupper-regs-df.
	* gcc.target/powerpc/ppc-target-1.c: Update tests to allow either
	VSX scalar operations or the traditional floating point form of
	the instruction.
	* gcc.target/powerpc/ppc-target-2.c: Likewise.
	* gcc.target/powerpc/recip-3.c: Likewise.
	* gcc.target/powerpc/recip-5.c: Likewise.
	* gcc.target/powerpc/pr72747.c: Likewise.
	* gcc.target/powerpc/vsx-builtin-3.c: Likewise.
