This testcase still ICEs.
Note clang, EDG and MSVC all reject it with a similar message here is clang's:
```
<source>:3:3: error: no matching function for call to object of type '(lambda
at <source>:3:3)'
3 | [] (decltype([]{})) {} ();
| ^~~~~~~~~~~~~~~~~~~~~~
<source>:3:3: note: candidate function not viable: requires 1 argument, but 0
were provided
3 | [] (decltype([]{})) {} ();
| ^ ~~~~~~~~~~~~~~
<source>:3:3: note: conversion candidate of type 'void (*)(decltype([] {
}))' (aka 'void (*)((lambda at <source>:3:16))')
```
