[Hexagon] Add coverage tests for CodeGen analysis and optimization passes (#183952) Add tests targeting Hexagon CodeGen analysis and optimization passes: - gen-pred-andn-orn.ll: HexagonGenPredicate pass exercising andn/orn logical operations, cmp-zero conversion paths, deeper predicate chains, and byte comparison classification. - memcpy-likely-aligned.ll: HexagonSelectionDAGInfo exercising the aligned memcpy specialization path. - constprop-fp-cmp.ll: HexagonConstPropagation exercising floating- point comparison constant folding paths. - sched-timing-classes.ll: Scheduling timing class coverage for various Hexagon instruction classes.
