Intrinsic Support for more vector APIs

[Deshpande, Vivek R]

Hi All

I have webrev for Intrinsic Support for some more vector APIs at this location.
http://cr.openjdk.java.net/~vdeshpande/Panama_VAPI/webrev.00/

I have added support for div, broadcast, zero, equal, lessThan, Blend for types Int
and div, lessThan, zero, broadcast for float and length vector APIs for 256 bit vectors.
Could you please take a look and review the patch.

Thanks.
Regards,
Vivek
