[SLP] Enable -slp-vectorize-hor by default.

Description

[SLP] Enable -slp-vectorize-hor by default.

Measurements primarily on AArch64 have shown this feature does not
significantly effect compile-time. The are no significant perf changes in LNT,
but for AArch64 at least, there are wins in third party benchmarks.

As discussed on llvm-dev, we're going to try turning this on by default and see
how other targets react to the change.
