    middle-end: don't lower past veclower [PR106063]

    Hi All,

    My previous patch can cause a problem if the pattern matches after veclower
    as it may replace the construct with a vector sequence which the target may
not
    directly support.

    As such don't perform the rewriting if after veclower unless the target
supports
    the operation.  If before veclower do the rewriting as well if the target
didn't
    support the original operation either.

    gcc/ChangeLog:

            PR tree-optimization/106063
            * match.pd: Do not apply pattern after veclower is not supported.

            * gcc.dg/pr106063.c: New test.
