IntelliSense and syntax highlight not working at all for function pointer callconv-s

[Sergio0694]

Version Used:

• VS2022 17.0.5
• VS2022 17.1 Preview 3

Steps to Reproduce:

1. Write any function pointer with explicit callconv(s), eg.:

delegate* unmanaged[Stdcall]<void> f0;
delegate* unmanaged[Cdecl]<void> f1;
delegate* unmanaged[MemberFunction, SuppressGCTransition]<void> f2;
delegate* unmanaged[Thiscall]<void> f3;
delegate* unmanaged[Fastcall]<void> f4;

2. Observe that syntax highlight is broken (the type is white)
3. Observe that IntelliSense is broken (hovering doesn't show the type info)

Expected Behavior:

• The modifiers should be colored (in green, as they're classes)
• Hovering on them should display the usual type info like on any other type

Actual Behavior:

• No syntax highlight at all
• No hovering tooltip at all

In case it matters, both issues also reproduce on casts, not just member declarations.

This is very low priority for us. We would take a suitably small and targetted fix here though.

This actually got already fixed. @CyrusNajmabadi I think it could be closed.

Okey dokey!
