This patch adds 3 tests that tests whether PLI (PADDI) is generated to load up
DImode constants, load up SImode constants, and adding 34-bit constants.

Once the appropriate patches to generate this code have been checked in (V7,
#1-3), can I check these new tests into the FSF trunk?

2019-11-14   Michael Meissner  <meissner@linux.ibm.com>

	* gcc.target/powerpc/paddi-1.c: New test to test using PLI to
	load up a large DImode constant.
	* gcc.target/powerpc/paddi-2.c: New test to test using PLI to
	load up a large SImode constant.
	* gcc.target/powerpc/paddi-3.c: New test to test using PADDI to
	add a large DImode constant.

	* gcc.target/powerpc/paddi-1.c: New test.
	* gcc.target/powerpc/paddi-2.c: New test.
	* gcc.target/powerpc/paddi-3.c: New test.

Changelogs say *what*, not *why*.  If you want to say what is tested,
say that in the testcases itself (you should, in fact; and more precise
than this please).

This will always succeed (it matches the ".file" line).
