Extended Description

Godbolt shows a clang 10 stacktrace for the following code:
https://godbolt.org/z/8az9zC

I wanted to build a template helper to transform a std::variant of the form
std::variant<type_tag<A>, type_tag<B>, ...>
into:
std::variant<A, B, ...>
.

[Clang] Fix instantiation of OpaqueValueExprs (Bug llvm#45964)
b5aef90 
The structured bindings decomposition of a non-dependent array in a dependent context (a template) were, upon instantiation, creating nested OpaqueValueExprs that would trigger assertions in CodeGen. Additionally the OpaqueValuesExpr's contained SourceExpr is being emitted in CodeGen, but there was no code for its transform in template instantiation. This would trigger other assertions such as when emitting a DeclRefExpr that refers to a VarDecl that is not marked as ODR-used.

This is all based on cursory deduction, but with the way the code flows from SemaTemplateInstantiate back to SemaInit, it is apparent that the nesting of OpaqueValueExpr is unintentional.

This commit fixes https://bugs.llvm.org/show_bug.cgi?id=45964 and possible other issues involving OpaqueValueExprs in template instantiations might be resolved.
