The testcase has been failing on BE because the compiler is simply storing the
value straight from the GPRs. The following patch fixes the issue by using 'r'
in an expression which forces the value back to a VSR. Verified the testcase
now passes for powerpc64 and still passes for powerpc64le. Ok for trunk?
