    CPUProfiler: Push deopt reason further to ProfileNode. · ce8701b2
    loislo authored
    1) create beefy RelocInfo table when cpu profiler is active, so if a function
    was optimized when profiler was active RelocInfo would get separate DeoptInfo
    for the each deopt case.
    
    2) push DeoptInfo from CodeEntry to ProfileNode.
    When deopt happens we put the info collected on #1 into CodeEntry and record stack sample.
    On the sampling thread we grab the deopt data and append it to the corresponding ProfileNode deopts list.
    
    Sample profile dump.

        0  (root) 0 #1
        1     29 #2
        5      test 29 #3
        3        opt_function 29 #4
                     deopted at 52 with reason 'not a heap number'
                     deopted at 71 with reason 'division by zero'
