Hi,

This bug fix patch fixes an assertion failure seen while auto-vectorizing conversion chain involving float16 type.
Constraining the container type for ConvF2HF IR to short type upfront , as relying on backpropagating narrow
type from memory operation  may not be sufficient if IR is succeeded by ConvHF2F as depicted by the include test case.

Best Regards,
Jatin
