`processMiniFPOrInt4Type` in SPIRVWriter was not handling `i16`, `i64`, and `<N x i8>` packed containers, causing an assert on forward translation. `OpSConvert` with an Int4 source in SPIRVReader was falling through to the generic SExt/Trunc path, causing `ConvertInt4ToInt8INTEL` to round-trip as a bare `sext`. Tests for `SPV_INTEL_float4` and `SPV_INTEL_int4` packed conversions are extended to cover all conversion instructions and container varieties.
