This pattern supports lowering of: vector.transfer_read to a combination of vector.load, arith.select and vector.broadcast if all of the following hold:

The transfer op is masked.
The memref is in buffer address space.
Stride of most minor memref dimension must be 1.
Out-of-bounds masking is not required.
If the memref's element type is a vector type then it coincides with the result type.
The permutation map doesn't perform permutation (broadcasting is allowed). Note: those conditions mostly come from TransferReadToVectorLoadLowering pass.
