Sanjay Patel baa325e1de [Analysis] add isSplatValue() for vectors in IR ...

We have the related getSplatValue() already in IR (see code just above the proposed addition).
But sometimes we only need to know that the value is a splat rather than capture the splatted
scalar value. Also, we have an isSplatValue() function already in SDAG.

Motivation - recent bugs that would potentially benefit from improved splat analysis in IR:
