    middle-end/121467 - split the Standard Pattern Names section

    The following splits the standard pattern names section into two
    (for now), listing vector related patterns separately.  It also
    adds a separate index for the many standard pattern names we have,
    something long overdue.

            * doc/gccint.texi: Add named pattern index with @mdindex.
            * doc/md.texi (Standard Pattern Names For Generation): Split
            table into two using subsections, splitting out vectorizer
            related standard patterns.  Use @mdindex for all standard
            pattern names.
