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?

* 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.
