6968367: can_post_on_exceptions is still using VM_DeoptimizeFrame in some places
Reviewed-by:

The fix for 6902182 changed some call sites where deopt is needed to
call directly into deoptimize_frame instead of using
VM_DeoptimizeFrame but it missed quite a few places, particularly in
the client compiler.  Instead of directly modifying each site to use
the appropriate version I modified Deoptimization::deoptimize_frame to
select the appropriate version, made VM_DeoptimizeFrame private, and
updated all call sites to use the main entry point.  Tested with all
the nsk JVMTI tests.
