[PATCH, rs6000] Fix instruction counts on powerpc64 test cases.
This patch fixes the assembler instruction counts for some test cases
that started failing due to changes in code generation. The targets
were adjusted a bit as well to avoid generating BE/LE endian code on
unsupported platforms.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu (power 8 and
power 9) and powerpc64be-unknown-linux-gnu (power 7 and power 8) with
no regressions. Is this ok for trunk?

* gcc/testsuite/gcc.target/powerpc/vsx-vector-6.p7.c: Update
instruction counts and target.
* gcc/testsuite/gcc.target/powerpc/vsx-vector-6.p8.c: Update
instruction counts.
* gcc/testsuite/gcc.target/powerpc/vsx-vector-6.p9.c: Update
instruction counts and target.
