Summary: Select folding in JumpThreading can create a conditional branch on a code patch that did not have one in the original program. This is not a valid transformation in sanitize_memory functions. Note that JumpThreading does select folding in 3 different places. Two of them seem safe - they apply to a select instruction in a BB that ends with an unconditional branch to another BB, which (in turn) ends with a conditional branch or a switch with the same condition.
