Add multilib variants for -march=rv64imafd, e.g. to support the BOOMv2 core.

Add -mcmodel=medany as a variant of the 64-bit multilibs for RTEMS.  The
rationale for this change is that several existing RISC-V chips map the
RAM at 0x80000000.  In RTEMS, we do not use virtual memory, so
applications will run at this location which is outside the +-2GiB range
in a 64-bit configuration.

Common systems like glibc and FreeBSD define int32_t to int.  This means
a lot of third party code works well in these cases:

  #include <stdint.h>

  void f(int32_t);

  void f(int);

  void g(int32_t *);

  void h(void)
  {
    int i;
    g(&i);
  }

On RTEMS you got however in C

  test.c:5:6: error: conflicting types for 'f'
    void f(int);
        ^
  test.c:3:6: note: previous declaration of 'f' was here
    void f(int32_t);
        ^
  test.c: In function 'h':
  test.c:12:4: warning: passing argument 1 of 'g' from incompatible
  pointer type [-Wincompatible-pointer-types]
    g(&i);
      ^
  test.c:7:6: note: expected 'int32_t * {aka long int *}' but argument
  is of type 'int *' void g(int32_t *);

and C++

  test.c: In function 'void h()':
  test.c:12:4: error: invalid conversion from 'int*' to 'int32_t* {aka
  long int*}' [-fpermissive]
    g(&i);
      ^~
  test.c:7:6: note:   initializing argument 1 of 'void g(int32_t*)'
    void g(int32_t *);
      ^

This was due to a Newlib speciality which uses long for int32_t if long
is a 32-bit type.  To ease the use of third party software in RTEMS we
override this Newlib option now and use int for int32_t if int is a
32-bit type.

    The traversal used by the write barrier insertion phase can sometimes
    wind up visiting new statements inserted during the traversal, which
    then results in duplicate / redundant write barrier guards. Example
    program to reproduce:
    
      package small
      type S struct {
            N *S
            K int
      }
      var G *S = &S{N: nil, K: 101}
    
    This patch changes the traversal code to keep track of statements
    already added and avoid processing them again later in the traversal.

There is no need to use an allocator of the correct value_type when
calling allocator_traits::construct and allocator_traits::destroy. The
existing node allocator can be used, instead of constructing a new

There's also no benefit to using __gnu_cxx::__alloc_traits instead of
