InstrProf: Increment the profile counter for all types of destructor

-fprofile-instr-generate does not emit counter increment intrinsics
for Dtor_Deleting and Dtor_Complete destructors with assigned
counters. This causes unnecessary [-Wprofile-instr-out-of-date]
warnings during profile-use runs even if the source has never been
modified since profile collection.

Patch by Betul Buyukkurt. Thanks!
