      Correctify instanceof and make it optimizable. · 5d875a57
      bmeurer authored
      The previous hack with HInstanceOfKnownGlobal was not only slower,
      but also very brittle and required a lot of weird hacks to support it. And
      what's even more important it wasn't even correct (because a map check
      on the lhs is never enough for instanceof).
      
      The new implementation provides a sane runtime implementation
      for InstanceOf plus a fast case in the InstanceOfStub, combined with
      a proper specialization in the case of a known global in CrankShaft,
      which does only the prototype chain walk (coupled with a code
      dependency on the known global).
      
      As a drive-by-fix: Also fix the incorrect Object.prototype.isPrototypeOf
      implementation.

      Revert of Externalize deoptimization reasons. (patchset #6 id:100001 of https://codereview.chromium.org/874323003/)
      
      Reason for revert:
      it broke the build
      
      Original issue's description:
      > Externalize deoptimization reasons.
      >
      > 1) The hardcoded strings were converted into DeoptReason enum.
      >
      > 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.

      Introduce LanguageMode, drop StrictMode. · c7851da4
      marja authored
      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).
