If a def is used as an condition before its definition, we should also
consider this a case to repair. When repairing, make sure we rewrite
any if conditions too.
Found in while inspecting a SPIR-V conversion from a 'continue block'

the beggining of the loop, and the condition in the branch ends up
defined afterwards.
