Vector API: stack overflow on Big Endian

[Paul Sandoz]

Thanks, that is helpful, so it's only re-bracket tests for lanewise conversion that fail.

This reinforces my suspicions that the actual output is fine, and the test assumes LE encoding in castByteArrayData, which I think takes a short cut for casting just for +ve integral types. Lanewise conversion skips floating point types and so is only partially tested. 

The method castByteArrayData needs to be reimplemented loading into a ByteBuffer, reading values, casting them, and storing them into a resulting buffer. Not difficult to do, just a little laborious.

Paul.
