### Overview
Upstream support for declaring, calling, and emitting virtual functions in CIR.
This is probably going to involve a lot of changes, including the introduction of vtables. The changes should be upstreamed in the smallest pieces possible and growing the support incrementally.
### Suggested minimal test case
```
class C {
int a; // Necessary until we have better handling for zero-member classes
virtual void vf();
}
int f() {
C c;
}
```
### Existing incubator tests
