Tweak the interpreter entries and 2nd level trace filter to capture more traces.

Tweak the interpreter entries and 2nd level trace filter to capture more traces.

Real changes:
1) Add a new entry point from JIT to the interpreter to request hot traces w/o
   doing chaining.
2) Increase the granularity of the secondary profile filter to match 64-byte
   chunks using 64 entries.

The remaining are just cosmetic changes.
