C++ Interop: Support reference types in fields and globals (#6187)
Implemented by generalizing the reference type support for parameters
and return values to other use cases.
The changes to the `method.carbon` test are due to to supporting the
reference types but not supporting the necessary conversions.
C++ Interop Demo:
```c++
// global.h
struct C {
int member = 0;
int& member_ref = member;
};
extern C& global;
```
```c++
// global.cpp
#include "global.h"
static C static_c;
C& global= static_c;
```
```carbon
// main.carbon
library "Main";
import Core library "io";
import Cpp library "global.h";
fn Run() -> i32 {
Core.Print(Cpp.global->member);
++(*Cpp.global->member_ref);
Core.Print(Cpp.global->member);
++(*Cpp.global->member_ref);
Core.Print(Cpp.global->member);
return 0;
}
```
```shell
$ clang++ -stdlib=libc++ -c global.cpp
$ bazel build toolchain:carbon && bazel-bin/toolchain/carbon compile main.carbon
$ bazel-bin/toolchain/carbon link global.o main.o --output=demo
$ ./demo
0
1
2
```
**Without this change**:
```shell
main.carbon:10:14: error: semantics TODO: `Unsupported: var type: C &`
Core.Print(Cpp.global->member);
^~~~~~~~~~
main.carbon:10:14: note: in `Cpp` name lookup for `global`
Core.Print(Cpp.global->member);
^~~~~~~~~~
```
Part of #6006 and #6186.
