[PATCH v2 1/3] vect: Make non-SLP paths unreachable in strided slp/elementwise.

[Robin Dapp]

From: Robin Dapp <rdapp....@gmail.com>

This replaces if (slp) with if (1) and if (!slp) with if (0).

gcc/ChangeLog:

        * tree-vect-stmts.cc (vectorizable_load): Make non-SLP paths
        unreachable.
