I do not understand this completely, in this branch `setImportDeclError` is
called so at next time we can not go into this branch again (for the same
`FromD`). (We can get the error and not go into this branch more than once but
get no error and go into the branch only once.)

Maybe we should not use a macro for this, specially not define the macro inside
the `struct` block. For the current tests it is sufficient to make a
std::string that contains something like `void f() { asm(""); }`.
