[vm/compiler] Use loop framework for AOT inline heuristics Rationale: Without proper execution counters, the inline AOT inliner marks every call site "cold", effectively disabling inlining altogether. This change introduces loop-based static heuristic that assumes statements nested inside loops are executed more frequently. This results in more inlining. Note: Conservative version is used for now which yields more performance without increasing code size too much. There is still a lot of performance left at the table which we could exploit if we fine tune heuristics regarding code size.
