    genemit: Split insn-emit.cc into several partitions.

    On riscv insn-emit.cc has grown to over 1.2 mio lines of code and
    compiling it takes considerable time.
    Therefore, this patch adjust genemit to create several partitions
    (insn-emit-1.cc to insn-emit-n.cc).  The available patterns are
    written to the given files in a sequential fashion.

    Similar to match.pd a configure option --with-emitinsn-partitions=3Dnum
    is introduced that makes the number of partition configurable.
