support auto-magic instrumentation post-mbr, post-syscall, post-cbr, post-ubr, and post-call?

The mbr and syscall part was PR 240265

These are fragile locations, and we originally disallowed instru there just due to implementation complexity. We do have dr_insert_mbr_instrumentation() and related routines.

The most compelling feature cases are post-ret, post-syscall, and post-call. For cbrs, dr_insert_cbr_instrumentation() seems sufficient.

Auto-magically adding post-call instrumentation would have made drwrap easier to implement.
