The preparser needs to log the usage of super properties and then update
the scope when we create the function later.

StatisticsExtension::GetCounters() has grown to repeat a lot of code
so to make it more maintainable and generate less machine code,
make it data driven. This makes a 64 bit Linux build 50 KB smaller.

This removed some inconsistent/duplicated code and made the testing
side entrance much simpler: Now it simply constructs a pipeline and
hands off to the "tail" of the normal pipeline.

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.

This is needed as normal chromium checkouts don't fetch
branch-heads.
These branches will also be replicated by GitHub and are
fetched when cloning from the repository.
The expected object size will be the same or smaller than
before as we currently push the same information onto the
candidates branch (which already is in refs/heads). The only
difference is the increasing number of refs in refs/heads.

Parser must be able to operate independent of Isolate and the V8 heap during
parsing. After the heap-independent phase, there is a heap dependent phase,
during which we internalize strings, handle errors, etc.
This makes Isolate (also via CompilationInfo) unaccessible during parsing, and
thus decreases the probability of accidental code changes which would add
heap-dependent operations into the heap-independent phase.
Since Isolate is also accessible via CompilationInfo, now CompilationInfo is
only passed to the entry points of parsing, and not stored in Parser.

Previously, emitting two more more unique source positions at the same pc would
generate two or more RelocInfo entries. Now, only the last emitted source
position for any pc is added to the RelocInfo.

Rename tools/vim/v8.ycm_extra_conf.py to .ycm_extra_conf.py, so every
YCM plugin (no matter if it's VIM or Emacs) should pick it up
automatically.
Also move the common tools/vim/ninja_output.py to tools/ninja/ as it's
also not related to VIM.

This error is exposed by this CL: https://codereview.chromium.org/817293005.
This CL set all Buildin JS function to optimization_disabled.
And set the bailout reason to "kBuiltinFunctionCannotBeOptimized". But in Runtime_SetCode() function.
It copied the the compiler_hints which include the "bool optimization_disabled" value,
But the corresponding Bailout reason is not copied.
This leads to the check error in "CompilationInfo::AbortOptimization(...)" function.
This issue is exposed on turbofan unsupported X87 platform. Crankshaft is invoked to compile
the typed array function Uint8Array.
