Add support for int return type in Carbon/C++ interop (#5114)
Adding support for importing C++ functions with `int` return type in
Carbon.
Part of #5063
Here is a demo of the functionality:
```c++
// hello_int.h;
auto foo_int() -> int;
```
```c++
// hello_int.cpp
#include "hello_int.h"
auto foo_int() -> int {
return 1;
}
```
```carbon
// main.carbon
library "Main";
import Cpp library "hello_int.h";
import Core library "io";
fn Carbon_foo(b: i32) {
Core.Print(b);
}
fn Run() -> i32 {
Carbon_foo(Cpp.foo_int());
return 0;
}
```
```
$ clang -c hello_int.cpp
$ bazel-bin/toolchain/carbon compile main.carbon
$ bazel-bin/toolchain/carbon link hello_int.o main.o --output=demo
$ ./demo
1
```
