Oh yes, I took the last free bit in FunctionDeclBits a couple of months ago :)
This is a tall order, but it may be possible to make room in there. For example:
```C++
LLVM_PREFERRED_TYPE(bool)
uint64_t IsDefaulted : 1;
LLVM_PREFERRED_TYPE(bool)
uint64_t IsExplicitlyDefaulted : 1;
```
It looks like `IsExplicitlyDefaulted` only makes sense if `IsDefaulted` is
true, and maybe your new stuff only makes sense if `IsDefaulted` is false, so
you can
probably share the `IsExplicitlyDefaulted` bit.
if that doesn't work, there are some other potential candidates.
For example, some bit fields only make sense if the function has a body, like
`UsesSEHTry`, and these bits would probably be free for you as well.
