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.

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

Just visit young array buffers during scavenge. Additionally keep the views in new space in a separate global list and move them to the corresponding array buffers when they get promoted.

This reduces young generation garbage collections when many array buffers are allocated.

  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.

   Parsing: Make Scope not know about Isolate.

  Scope, like Parser, must be able to operate independent of Isolate and the V8
  heap (for background parsing). After the heap-independent phase, there is a heap
  dependent phase, during which we do operations such as scope anaylysis.

  This CL makes the phases explicit by not telling Scope about the Isolate too
  early (during the heap-independent phase, Scope should know nothing about
  Isolate). This decreases the probability of accidental code changes which would
  add heap-dependent operations into the heap-independent phase.

original commit message:

  1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
     because it also has raw position. Also the old name clashes with DeoptReason enum.

  2) c_entry_fp assignment call was added to EntryGenerator::Generate
     So we can calculate sp and have a chance to record the stack for the deopting function.
     btw it makes the test stable.

  3) new kind of CodeEvents was added to cpu-profiler

  4) GetDeoptInfo method was extracted from PrintDeoptLocation.
     So it could be reused in cpu profiler.
