5d68529be2 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.

86cae1633c Propagate DeoptInfo to cpu-profiler
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.

0ca9bef37f Get rid of PreParserScope.
It's unnecessary; PreParser can just use normal Scopes for the things it needs
to track. Note: the only functionalities of PreParserScope were keeping track of
the scope stack, and for each scope, the scope type and language mode. Those are
now done by Scope. PreParser doesn't yet put variables into scopes (that will be
done in a follow up).

   * Relaxed the type of code_stub().

   * Made GetCodeKind() public, it effectly was like this, anyway.

   * Const-corrected GetStubType().

   2) Deopt comment were converted into a pair location and deopt reason entries so
      the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.

   3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.

original commit message:

  Retry "Use a WeakCell in the CallIC type vector."

  The first try failed because I needed to make a better distinction

  It was also blocked by an issue in super constructor calls.
  This fix (https://codereview.chromium.org/892113002/) needs to land

4ee5161962 X87: Introduce LanguageMode, drop StrictMode.
port c7851da4ae (r26419)

original commit message:

  Introduce LanguageMode, drop StrictMode.

  This enables adding more language modes in the future.

  For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to
  use a sequence of language modes which are progressively stricter, but we can
  express the language mode as combination of features.

  For now, LanguageMode can only be "sloppy" or "strict", and there are
  STATIC_ASSERTS in places which need to change when more modes are added.

  LanguageMode is a bit like the old LanguageMode when "extended" mode was still
  around (see https://codereview.chromium.org/8417035 and
  https://codereview.chromium.org/181543002 ) except that it's transmitted through
  all the layers (there's no StrictModeFlag).

port 64f81870ee (r26414)

original commit message:

  Super Constructor Calls need to use a vector slot, not an ic slot.

  The Ast Call node is accustomed to using a vector IC slot for the
  cases when it uses a CallIC. The super constructor work alters this
  somewhat by using a CallConstructStub instead, however the
  CallConstructStub expects a vector slot and not a vector ic slot.
  This distinction needs to be maintained because slots and ic slots
  have different clearing strategies and are handled differently.

  Megamorphic KeyedLoadIC needs special handling for vector ics.

  When --vector-ics is true, we still tail-call to the hand-written

  the megamorphic cache, it needs to deal properly with the vector and
  slot registers. Achieve this with a sentinel vectors/slot combo.
