  Fix analyzer crash on 'StructuralValue' (#79764)

`OpaqueValueExpr` doesn't necessarily contain a source expression.
Particularly, after #78041, it is used to carry the type and the value
kind of a non-type template argument of floating-point type or referring
to a subobject (those are so called `StructuralValue` arguments).

This fixes #79575.
