    Fix optimize_mask_stores profile update

    While looking into sphinx3 regression I noticed that vectorizer produces
    BBs with overall probability count 120%.  This patch fixes it.
    Richi, I don't know how to create a testcase, but having one would
    be nice.

    Bootstrapped/regtested x86_64-linux, will commit it shortly.

    gcc/ChangeLog:
