We should probably add a release note that says we partially implement CWG 2569
(just the `decltype` portion) and that the core issue has not yet been approved
by WG21 but the changes are needed to keep libstdc++ working.

+ /*TemplateKWLoc=*/nullptr, Name))
+ return ExprError();
+ return Actions.ActOnMutableAgnosticIdExpression(getCurScope(), SS, Name);
----------------
Sorry, I forgot to mention this before, but there should be some test coverage
for this case to make sure the behavior is still reasonable. Something like:
```
void whatever() {
[=]<typename T = decltype(b)>(){};
}
```
(I'd expect we get some sort of lookup error for `b`.)
