1) Added PrintOpto guard to noisy Verbose prints in Compile::process_for_unstable_if_traps and Parse::catch_call_exceptions.

2) Removed noisy Verbose in ciEnv::record_best_dyno_loc, which looked like a leftover from implementation of [JDK-8271911](https://bugs.openjdk.org/browse/JDK-8271911).
I also rearranged the if statement around Verbose and removed the TODO comment.
@dean-long is the TODO still relevant? In case it is still relevant, I think we should create a separate enhancement for further investigation rather than keeping it in the comments.

-------------

Commit messages:
 - Rewrote the if statement in record_best_dyno_loc
 - Removed noisy Verbose in ciEnv.cpp
 - 8293069: Guarded Verbose prints additionally with PrintOpto in compile.cpp and doCall.cpp. This avoids increased printing when setting the Verbose flag without the PrintOpto flag.
