  -----------
  [Clang] Correct the DeclRefExpr's Type after the initializer gets instantiated (#133212)

The instantiation of a VarDecl's initializer might be deferred until the
variable is actually used. However, we were still building the
DeclRefExpr with a type that could later be changed by the initializer's
instantiation, which is incorrect when incomplete arrays are involved.

Fixes #79750
Fixes #113936
Fixes #133047
