[vector] RFR: Unify VectorMaskCmp shape between x86 and aarch64

[Yang Zhang]

Hi Vladimir

I verified this patch on aarch64, vector api tests are passed.
It looks good to me. 

19473 instruct vcmeq4I(vecX dst, vecX src1, vecX src2, immI cond)
You add one input parameter "immI cond", but don't use it. I will create another patch to use " immI cond" to combine compare operations.

Regards
Yang

Get rid of platform-specific differences in VectorMaskCmp.

Testing: jdk/incubator/vector tests

The patch is against vectorIntrinsics branch.
