    vectorizer: Fix riscv build [PR120042]

    r15-9859-ga6cfde60d8c added a call to dominated_by_p to tree-vectorizer.h
    but dominance.h is not always included; and you get a build failure on
riscv building
    riscv-vector-costs.cc.

    Let's add the include of dominance.h to tree-vectorizer.h

    Pushed as obvious after builds for riscv and x86_64.

    gcc/ChangeLog:

            PR target/120042
            * tree-vectorizer.h: Include dominance.h.
