Now that we are stack allocating arrays, the array reference may be either TYP_BYREF or TYP_I_IMPL, so try and recognize those cases when possible. In particular for OSR methods the array allocation may "disappear" once we redirect flow to the OSR entry, so relying on VN is insufficient. Fixes dotnet#112429 (benchmark regression where we're measuring OSR code)

(mostly just want to see lvaGetDesc instead of raw access into lvaTable)
