      [api] Add an ApiCheck for Function::Call on a null handle · e520f4e5
      Adam Klein authored 
      This would help separate such API misuses from other Invoke() crashes
which indicate crashes in generated code.

      PPC/s390: Reland [turbofan] Implement on-stack returns (Intel) · cae7667c
      Junliang Yan authored 
      Port bd732f7d

Original Commit Message:

    The original CL introduced a test which uses a random number generator.
    I disable the test for now, which is okay because this CL adds to a
    work-in-progress feature anyways, and I will fix the problem in another
    CL.

    Original description:
    Add the ability to return (multiple) return values on the stack:

    - Extend stack frames with a new buffer region for return slots.
      This region is located at the end of a caller's frame such that
      its slots can be indexed as caller frame slots in a callee
      (located beyond its parameters) and assigned return values.
    - Adjust stack frame constructon and deconstruction accordingly.
    - Extend linkage computation to support register plus stack returns.
    - Reserve return slots in caller frame when respective calls occur.
    - Introduce and generate architecture instructions ('peek') for
      reading back results from return slots in the caller.
    - Aggressive tests.
    - Some minor clean-up.

    So far, only ia32 and x64 are implemented.

      [wasm] Allow to restart background tasks during streaming compilation · 2c3fae96
      Andreas Haas authored 
      In a certain scenario streaming compilation got stuck and did never
finish. This CL fixes this issue.

Scenario:
* Streaming compilation starts
* The compilation tasks execute all compiation units in the working
  queue and set the finished_ flag to true.
* New data arrives over streaming
* The compilation tasks compile so fast that the executed_units_ queue
  gets full. The compilation tasks stop executing and wait for the
  finisher task to restart them.
* The finisher task does not restart the compilation tasks because the
  finished_ flag is set.

With this CL I remove the finished flag and instead look at the size
of the working queue directly.

In addition I added a test which does not actually reproduce this
scenario but seems good to have anyways.
