This is V10 patch #10. It adds 3 new tests to verify that we generate PADDI/PLI
for large constants when -mcpu=future is used.
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00843.html

This test passes when the preceeding patches are applied.  Can I check this in?

	* gcc.target/powerpc/prefix-add.c: New test for -mcpu=future
	generating PADDI for large constant adds.
	* gcc.target/powerpc/prefix-di-constant.c: New test for
	-mcpu=future generating PLI to load up large DImode constants.
	* gcc.target/powerpc/prefix-si-constant.c: New test for
	-mcpu=future generating PLI to load up large SImode constants.
