[vectorIntrinsics] VectorTest cleanup

[Viswanathan, Sandhya]

Please find below a webrev which cleans up VectorTest implementation for X86.
There is also a change in the second source parameter being passed for anyTrue to VectorIntrinsics
from being same as src1 to mask all true.
Aarch64 implementation does not use the second source parameter for anyTrue so the change shouldn't affect Aarch64.
