    Revert of CPUProfiler: Push deopt reason further to ProfileNode. (patchset #1 id:1 of https://codereview.chromium.org/919953002/)
    
    Reason for revert:
    static initializers broke the build
    
    Original issue's description:
    > CPUProfiler: Push deopt reason further to ProfileNode.
    >
    > 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.

    >                  deopted at 52 with reason 'not a heap number'
    >                  deopted at 71 with reason 'division by zero'
