RFR: 8366861: Phase AFTER_LOOP_OPTS printed even though the method has no loops [v2]

[Saranya Natarajan]

> **Issue**
> When a test program with no loop is run with flag `-XX:PrintPhaseLevel=3,` the output prints `PHASE_AFTER_LOOP_OPTS `but does not print `PHASE_BEFORE_LOOP_OPTS`
> 
> **Solution** 
> This simple fix introduces a variable  `_print_phase_loop_opts` that caches the value of `has_loops()` before loop opts pass to make sure that `PHASE_AFTER_LOOP_OPTS` gets printed every time `PHASE_BEFORE_LOOP_OPTS` is printed.
