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.

original commit message:

   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.

port 86cae163 (r26545)

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.

This comment used to have a (commented-out) ASSERT attached to it.
But that ASSERT was removed years ago, so the comment is now a
non-sequitar.

A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),
so we need to avoid them. This CL removes almost all of them, the
remaining 2 call sites in (for testing only) will be handled in a
separate CL. Things which have been changed:

  * Linkage is basically a decorator for CallDescriptor now.

  * ChangeLowering doesn't need Linkage at all.

  * JSGenericLowering doesn't need a full CompilationInfo*, just a
    single flag.

  * JSContextSpecializer doesn't need the full CompilationInfo, just a
    Context.

  * Removed unused CompilationInfo from SimplifiedLoweringTester.

This nicely decouples things already a bit more, but there's still
work to do...
