loislo d23ab23b05 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.

Getting the Code

Checkout depot tools, and run

fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

git pull origin gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
