There's no need to check for that here, because we also run diagnoseDeclRefExportability() on declarations referenced from inlinable code. This changes some diagnostics; we now produce the same diagnostic for references to SPI types in declaration signatures and for references to non-type SPI declarations in inlinable function bodies. Also note that the old inlinable reference diagnostic no longer has to handle the 'public' and 'open' access levels, which previously happened for '@_spi'; so I changed those entries in the %select to %error.
