PUSHED: [PATCH 14/14][Vectorizer] Tidy up vect_create_epilog / use_scalar_result

[Alan Lawrence]

After recent updates, tree-vect-loop.c is in the same state as when this cleanup 
patch was first written and approved, so I've just pushed it as r/217580.

Cheers,
Alan

Following earlier patches, vect_create_epilog_for_reduction contains exactly
one case where extract_scalar_result==true. Hence, move the code 'if
(extract_scalar_result)' there, and tidy-up/remove some variables.

Ok.

Thanks,

gcc/ChangeLog:

        * tree-vect-loop.c (vect_create_epilog_for_reduction): Move code for
        'if (extract_scalar_result)' to the only place that it is true.
