[PATCH][rs6000] Add vec_init support for 750CL paired vectors and fix movv2sf_paired

Subject: [PATCH][rs6000] Add vec_init support for 750CL paired vectors and fix movv2sf_paired

Hello,

This patch adds vec_init support for the paired vectors by introducing
a new function: paired_expand_vector_init ().

It also includes a fix to the movv2sf_paired instruction description
regarding move of an easy vector constant.

The patch was tested on ppc64 (only c).

OK for mainline?

Thanks,
Revital
