codegen: separate getAnonDeclVAddr into lowerAnonDecl and the former

Implement the stub for Elf. I believe that separating the concerns, namely, having an interface function that is responsible for signalling the linker to lower the anon decl only, and a separate function to obtain the decl's vaddr is preferable since it allows us to handle codegen errors in a simpler way.
