        tree: Add include to tm_p.h to tree.cc [PR120866]
    
    broke SPARC bootstrap:
    
    In file included from ./tm_p.h:4,
                     from /vol/gcc/src/hg/master/local/gcc/tree.cc:35:
    /vol/gcc/src/hg/master/local/gcc/config/sparc/sparc-protos.h:46:47: error: 
use of enum ‘memmodel’ without previous declaration
       46 | extern void sparc_emit_membar_for_model (enum memmodel, int, int);
          |
    
    Fixed by including memmodel.h.
    
    Bootstrapped without regressions on sparc-sun-solaris2.11 and
    i386-pc-solaris2.11.
