tree-optimization/102318 - reduction epilogue re-use
This refines the fix for PR102226 to do the mode conversion
from V2DI to VNx2DI separately from the sign-conversion, retaining
the signedness of the saved accumulator as before the original fix.

* tree-vect-loop.c (vect_transform_cycle_phi): Revert
previous change and do the mode conversion separately from
the sign conversion.
