      Reland "Support Intel VTune ITT API" · 0b812b72
      Zhang, Shiyu authored 
      This is a reland of 5f5b4b04

Original change's description:
> Support Intel VTune ITT API
> 
> Add VTune domain support extension to use VTune Domain/Task API and
> tagging trace data for particular JS code block.
> 
> How to use:
> 1. Set `"checkout_ittapi" = True` in the custom_vars section of .gclient
> file to download intel/ittapi by 'gclient sync'
> 2. Build d8 with gn build flag 'v8_enable_vtunetracemark = true'
> 3. Run d8 with flag '--enable-vtune-domain-support'
> 
> The Vtune Domain/Task API can be invoked from JS to mark JS code block.
> You can mark the start of a JS task by
>     vtunedomainmark(domain_name, task_name, "start")
> and the end of a task by
>     vtunedomainmark(domain_name, task_name, "end")
> Tasks can nest.
> 
> The VTune API (ittapi) is integrated as an external third party library
> while the v8_vtune_jit also relies on the VTune ittapi. We have another
> patch almost ready which refactors the v8_vtune_jit related code to
> depend on the third_party/ittapi. We will submit the refactored v8_vtune_jit
> code after this patch stabilized and landed.

      [tests] Exercise Turbofan's instruction scheduling · ed0dce9d
      Georg Neis authored 
      Turbofan's instruction scheduling is currently only enabled for
mksnapshot and has thus little test coverage. This CL introduces two
new test variants, "instruction_scheduling" and
"stress_instruction_scheduling", and activates them on a selection of
bots.

      Reland "Activate is_offcial_build option for perf builders" · 38e59494
      Liviu Rau authored 
      This reverts commit 5a7c5879.

Reason for revert: The build time improved since we compile only
the d8 target now and removed the packaging step from the v8 recipe.

Original change's description:
> Revert "Activate is_offcial_build option for perf builders"
>
> This reverts commit b3c6e1ac.
>
> Reason for revert: The build time incresed significantly. We want to investigate if we can reduce it by removing the 'packaging' step.

      Reland "Unconditionally enable snapshot builds and remove 'v8_use_snapshot'" · 69efc4c3
      Simon Zünd authored 
      This is a reland of 1c56974f

This is a plain reland of the original CL. The original CL was speculatively
reverted, but ended up not being the cause for bot failures.

Original change's description:
> Unconditionally enable snapshot builds and remove 'v8_use_snapshot'
>
> This CL removes 'v8_use_snapshot' and the usages of the implied
> V8_USE_SNAPSHOT define. One test runner unittest was updated to use the
> "asan" variant instead of the now obsolete "no_snap" variant.
