This function adds (StartIdx * Step, (StartIdx + 1) * Step, (StartIdx + 2) * Step, ...) to each vector element of Val.
The sequence starts at StartIndex. Opcode is relevant for FP induction variable.

Checks if C is uniform across all VFs and UFs.
It is considered as such if it is either defined outside the vector region or its operand is known to be uniform across all VFs and UFs (e.g. VPDerivedIV or VPCanonicalIVPHI). TODO: Uniformity should be associated with a VPValue and there should be a generic way to check.
