This patch adds 3 tests for the PADDI instruction.  This was originally part of
V5 patch #12, but it was split out.

2019-10-15   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.
