The failure to intrinsify seems to stop the compilation of the method, leads to IR verification failure. The patch simply changes the argument of vector cast methods to correct types.

I think this update likely works around a bug when using `-XX:+UseKNLSetting` and the loading of 512-bit vectors, such as `IntVector` from `byte[]`. Hopefully the testing will confirm the workaround.

@jatin-bhateja could review the set of tests for each AVX variant, esp. for 512 bits and check if we are missing cases?
