kadircet added inline comments.

================
Comment at: clang-tools-extra/clangd/CodeComplete.cpp:1184
-      auto Name = Ident->getName();
-      if (!Name.empty())
-        ParamNames.insert(Name.str());
----------------
we were never recording unnamed params before, now they'll be surfaced during 
comment code completions. can you either keep dropping them here or on the code 
completion generation side (~line 1997)


================
Comment at: clang/include/clang/Sema/CodeCompleteConsumer.h:1057
+        : Kind(CK_Aggregate), AggregateType(Aggregate) {
+      assert(Aggregate != nullptr);
+    }
----------------
we don't have assertions in other cases, why here? (i think we should have it 
in other cases too, just wondering if there are any valid states where we 
construct an overloadcandidate from nullptr)


================
Comment at: clang/lib/Sema/CodeCompleteConsumer.cpp:522
+    if (const auto *CRD = dyn_cast<CXXRecordDecl>(AggregateType))
+      Count += CRD->getNumBases();
+    return Count;
----------------
i think this is only valid for c++17 onwards `If the number of initializer 
clauses exceeds the number of members and bases (since C++17) to initialize, 
the program is ill-formed.` (same for param type/decl)

it gets even more complicated, since one doesn't have to nest initialization of 
base class fields, e.g this is valid:
```
struct X
{
    int a;
    int b;
};

struct Y : X
{
    int c;
};

Y y1{ {1,2}, 3};
Y y2{ 1, 2, 3 }; // both of these set a=1, b=2, c=3
```


================
Comment at: clang/lib/Sema/SemaCodeComplete.cpp:6031
+                                         ArrayRef<Expr *> Args) {
+  constexpr unsigned Invalid = std::numeric_limits<unsigned>::max();
+
----------------
also `static`
