[Clang] Fix ICE in SemaOpenMP with structured binding (#104822) Fixes https://github.com/llvm/llvm-project/issues/104810. Clang currently crashes on the following program: ``` struct S { int i; }; auto [a] = S{1}; void foo() { a; } ``` when `-fopenmp` is enabled. Because `a` is neither `VarDecl` nor `FieldDecl`. It's a `BindingDecl` that's not handled in `SemaOpenMP.cpp`'s `getCanonicalDecl`. It appears to me that this pattern matching is merely just for a refined return type of the overrides. It can also be achieved with just using the virtual `Decl::getCanonicalDecl()` instead. Do the final casting should be safe for `ValueDecl`s. 2024-08-19 14:06:10 -07:00			`// RUN: %clang_cc1 -fopenmp -fsyntax-only %s`
