    '#include "tm_p.h"' in 'gcc/rust/backend/rust-tree.cc'

broke rust bootstrap on SPARC:

In file included from ./tm_p.h:4,
                 from /vol/gcc/src/hg/master/local/gcc/rust/backend/rust-tree.cc:38:
/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.  Tested on sparc-sun-solaris2.11 and
i386-pc-solaris2.11.
