[i386, AVX-512F, pr58269] Partial fix for PR58269: properly initialize last EXT REX SSE register.

[Kirill Yukhin]

Hello,
Here is a patch to fix pr58269.
Actually this is not a full fix, but an obvious part.

ChangeLog entry:
2013-09-06  Kirill Yukhin  <kirill.yuk...@intel.com>

        PR target/58269
        * gcc/config/i386/i386.c (ix86_conditional_register_usage):
        Proper initialize extended SSE registers.

Bootstrap pass.

Ok for trunk?
