Re: testsuite: Enable and adjust powerpc fold-vec-extract/insert testcases

git commit badeac77f552 changed expected number of addi instructions,
causing these fails on powerpc-linux.

I'm not at all sure why we are counting addi.  On linux I see
eight in fold-vec-insert-int-p9.c tearing down the stack frame in
function epilogues, and four in
        addi 9,1,16
        lvewx 0,0,9
For aix you have the above four but with a -16 offset.  There are no
stack frames, and you have four addressing stack red-zone as
        addi 9,1,-64

fold-vec-extract-char.p9.c on linux just has epilogue addi, aix has
red-zone addressing.  The same for fold-vec-extract-int.p9.c,
fold-vec-extract-longlong.p7.c and fold-vec-extract-longlong.p8.c.

It seems silly to count addi in a function epilogue, and fragile to
count them in code.  So remove the ilp32 addi checks.

	* gcc.target/powerpc/fold-vec-extract-char.p9.c: Don't check addi
	count for ilp32.
	* gcc.target/powerpc/fold-vec-extract-int.p9.c: Likewise.
	* gcc.target/powerpc/fold-vec-extract-longlong.p7.c: Likewise.
	* gcc.target/powerpc/fold-vec-extract-longlong.p8.c: Likewise.
	* gcc.target/powerpc/fold-vec-insert-int-p9.c: Likewise.
