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. > [Top down]: > 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' > > BUG=452067 > LOG=n > > Committed: https://crrev.com/ce8701b247d3c6604f24f17a90c02d17b4417f54 > Cr-Commit-Position: refs/heads/master@{#26615} TBR=jarin@chromium.org,svenpanne@chromium.org,yurys@chromium.org,alph@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=452067 Review URL: https://codereview.chromium.org/915173005 Cr-Commit-Position: refs/heads/master@{#26616}
