Support reduction def re-use for epilogue with different vector size
The following adds support for re-using the vector reduction def
from the main loop in vectorized epilogue loops on architectures
which use different vector sizes for the epilogue. That's only
x86 as far as I am aware.

* tree-vect-loop.c (vect_find_reusable_accumulator): Handle
vector types where the old vector type has a multiple of
the new vector type elements.
(vect_create_partial_epilog): New function, split out from...
(vect_create_epilog_for_reduction): ... here.
(vect_transform_cycle_phi): Reduce the re-used accumulator
to the new vector type.
* gcc.target/i386/vect-reduc-1.c: New testcase.
