is_load_store predicate

CodeArtifact

`is_load_store` is a Boolean predicate over `instr` values that classifies load/store instructions by combining word, halfword, and byte load/store predicates. In the cited HOL-TestGen case study, it is used as a precondition to restrict generated tests to load/store operations and is also lifted with `list_all` to constrain instruction sequences.
