tree-optimization/101462 - fix signedness of reused reduction vector

This fixes the partial reduction of the reused reduction vector to
carried out in the correct sign and the correctly signed vector
recorded for the skip edge use.

* tree-vect-loop.c (vect_transform_cycle_phi): Correct sign
conversion issues with the partial reduction of the reused
vector accumulator.
