    [debug] implement break on entry for builtin functions. · 876f37c3
    Yang Guo authored
    We reuse most of the infrastructure to set break points, with minor
    differences when we encounter functions where we can only break on entry:
    - PrepareFunctionForBreakPoints simply deopts all functions.
    - Break point objects have the canonical source position 0.
    - Break point is set/checked/cleared via bit on the DebugInfo.
    - Debug::Break do not continue stepping since stepping is implemented via
      regular break points and therefore do not interfere with break on entry.
    
    I promise to add more tests.
