// Validate that an IR module obeys the invariants we need to enforce.
// For example:
//
// * Confirm that linked lists for children and for use-def chains are consistent
// (e.g., x.next.prev == x)
//
// * Confirm that parent/child relationships are correct (e.g., if is `x` is in
// `y.children`, then `x.parent == y`
//
// * Confirm that every operand of an instruction is valid to reference (i.e., it
// must either be defined earlier in the same block, in a different block that
// dominates the current one, or in a parent instruction of the block.
//
// * Confirm that every block ends with a terminator, and there are no terminators
// elsewhere in a block.
//
// * Confirm that all the parameters of a block come before any "ordinary" instructions.
