LWG 3076 basic_string CTAD ambiguity
When deduction guides are supported by the compiler (i.e. for C++17 and
later) replace two basic_string constructors by constrained function
templates as required by LWG 3075. In order to ensure that the pre-C++17
non-template constructors are still exported from the shared library
define a macro in src/c++11/string-inst.cc to force the non-template
declarations (this isn't strictly needed yet, because the string
instantiations are compiled with -std=gnu++11, but that is likely to
change).

RTEMS: Prefer int for int32_t
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.

compiler: avoid introducing redundant write barriers
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.
