[Carbon/C++ interop] Add support for C++ overloaded functions (#5891)
As proposed in [Carbon: C++ interop for overloaded functions and function templates](https://docs.google.com/document/d/1KUxumZtNe3mY3TsjW2s_ZADOlAaFlrtsLKHVILtqIaM/edit?tab=t.0), Clang is used to perform the overload resolution using C++ rules, when an overloaded C++ set is called from Carbon. Once a function is selected, it's converted into a Carbon function and called using the Carbon rules including argument conversions. A single non-templated function is treated the same way as an overload set and the same rules apply for its call. Template functions are not supported yet. Demo: a) Non-templated function calls: ```c++ // --- overloads.h auto foo(int a, short b) -> void; auto foo(double a) -> void; auto foo(int a) -> void; ``` ```c++ // overloads.cpp #include "overloads.h" #include <cstdio> auto foo(int a, short b) -> void { printf("hello from foo_int_short(%d, %d) \n", a, b); } auto foo(double a) -> void { printf("hello from foo_double(%f) \n", a); } auto foo(int a) -> void { printf("hello from foo_int(%d) \n", a); } ``` ```c++ library "Main"; import Cpp library "overloads.h"; fn Run() -> i32 { Cpp.foo(1.1 as f64); return 0; } ``` ``` $ clang -c overloads.cpp $ bazel-bin/toolchain/carbon compile main.carbon $ bazel-bin/toolchain/carbon link overloads.o main.o --output=demo $ ./demo hello from foo_double(1.100000) ``` b) Constructors: ```c++ // --- constructor_overloads.h class C { public: C(); C(int a, int b); }; ``` ```c++ // constructor_overloads.cpp #include "constructor_overloads.h" #include <cstdio> C::C() { printf("hello from C() \n"); } C::C(int a, int b) { printf("hello from C(%d, %d) \n", a, b); } ``` ```c++ library "Main"; import Cpp library "constructor_overloads.h"; fn Run() -> i32 { let c1: Cpp.C = Cpp.C.C(); let c2: Cpp.C = Cpp.C.C(1, 2); return 0; } ``` ``` $ clang -c constructor_overloads.cpp $ bazel-bin/toolchain/carbon compile main.carbon $ bazel-bin/toolchain/carbon link constructor_overloads.o main.o \--output=demo $ ./demo hello from C() hello from C(1, 2) ``` Follow-ups: - `Cpp.foo({})` - proper handling of struct literals as call args. - Fix access for overloaded sets. - Fix tests: - Method calls: `error: missing object argument in method call [MissingObjectInMethodCall]` in tests. - Fix `toolchain/check/testdata/interop/cpp/import.carbon` test. - Fix `enums` support. - Fix `str` -> `std::string_view` mapping. Part of #5915
