    m2rte.cc reduce include headers and correct build dependencies.
    
    2022-05-16   Gaius Mulley   <gaius.mulley@southwales.ac.uk>
    
    This patch corrects the dependencies to build m2rte.so in
    Make-lang.in.  It also reduces the number of headers used in
    m2rte.cc.
    
    gcc/m2/ChangeLog:
    
            * plugin/m2rte.cc (alias.h, predict.h, tm.h,
            stringpool.h, toplev.h, basic-block.h, hash-table.h,
            vec.h, ggc.h, basic-block.h, tree-ssa-alias.h,
            internal-fn.h, gimple-fold.h, tree-eh.h, gimple-expr.h,
            is-a.h):  Header file includes removed.
            (plugin/m2rte$(exeext).so) Make dependent upon
            $(GCC_HEADER_DEPENDENCIES_FOR_M2) and insn-addr-common.h.
