Modify IRGen to emit “anonymous” string constants with names of the form `@.str.<len>.<contents>` (with a special mangling for internal `\0` characters). This makes it much easier to write IRGen tests that check for the contents of strings, because matching the constant name also implies that the constant has the expected content.
