[PATCH 1/3] Do not use STMT_VINFO_VECTYPE in vectorizable_reduction

[Richard Biener]

There's one use of STMT_VINFO_VECTYPE in vectorizable_reduction
where I'm only 99% sure which SLP_TREE_VECTYPE to replace it with
(vectorizable_reduction needs a lot of post-only-SLP TLC).  The
following replaces it with the hopefully appropriate one.

Bootstrapped and tested on x86_64-unknown-linux-gnu, cross-tested
aarch64-linux-gnu, pushed.

        * tree-vect-loop.cc (vectorizable_reduction): Replace
        STMT_VINFO_VECTYPE use with SLP_TREE_VECTYPE.
