Kerry McLaughlin 4bee3197f6 [SVE][CodeGen] Extend isConstantSplatValue to support ISD::SPLAT_VECTOR
Updated the affected scalable_of_scalable tests in sve-gep.ll, as isConstantSplatValue now returns true in DAGCombiner::visitMUL and folds `(mul x, 1) -> x`

++ SVE CodeGen Warnings ++

When the WARN check lines fail in the SVE codegen tests it most likely means you
have introduced a warning due to:
1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
   when the type is a scalable vector.
2. Relying upon an implicit cast conversion from TypeSize to uint64_t.

For generic code, please modify your code to work with ElementCount and TypeSize directly.
For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
Please refer to the code where those functions live for more details.
