Summary: When evaluating an expression referencing a constexpr static member variable, an error is issued because the PDB does not specify a symbol with an address that can be relocated against. Rather than attempt to resolve the variable's value within the IR execution, the values of all constants can be looked up and incorporated into the AST of the record type as a literal, mirroring the original compiler AST. This change applies to DIA and native PDB loaders.
