`Sema::getCurFunctionDecl(AllowLambda = false)` returns a nullptr when the lambda declaration is outside a function (for example, when assigning a lambda to a static constexpr variable). This triggered an assertion in `SemaAMDGPU::CheckAMDGCNBuiltinFunctionCall`. Using `Sema::getCurFunctionDecl(AllowLambda = true)` returns the declaration of the enclosing lambda. Stumbled with this issue when refactoring some code in CK.
