[PATCH 2/2] Enable auto-vectorization for PowerPC 750CL paired-single instructions

Hello,

This patch adds the relevant support in the vectorizer testsuite to
auto-vectorize the 750CL paired-single instructions.  It also contains
new tests.

Bootstrapped and tested together with the patch (1/2).

OK for mainline?

Thanks,
Revital
