      Add {CancelableTaskManager} to handle {Cancelable} concurrent tasks. · 60e7ea8a
      mlippautz authored 
      This change binds each {Cancelable} task to a so-called {CancelableTaskManager},
which is then used to handle concurrent cancelation as well as synchronizing
shutdown for already running tasks.  Since ownership of tasks is transferred to
the platform executing a task (destructor), handling in the manager uses integer
ids. Note that this also mitigates (modulo integer size) the ABA problem.

All handling of {Cancelable} tasks is now encapsulated into the corresponding
manager, which is instantiated for each isolate.

      Fix harmony sloppy block scoping dynamic redeclaration check · fd3ff03d
      adamk authored 
      The previous code did not properly check for harmony const when
doing the dynamic redeclaration check. This was masked in the
test because each eval had an initializer, and the initializer was what
triggered the exception.

This patch tightens the test by removing initializers and fixes the bug in
DeclareLookupSlot.

Also change the test to use assertThrows where possible.

      PPC: [turbofan] Better and more sane support for tail calls · cf2f6b80
      mbrandy authored 
      Port ff283f7d

Original commit message:
    * Limit triggering of tail calls to explicit use of a new inline runtime
      function %_TailCall. %_TailCall works just like %_Call except for using
      tail-calling mechanics (currently only in TF).
    * Remove hack that recognized some specific usages of %_Call and converted them
      into tail calls.
    * Support tail calls for all calls where the number of callee stack parameters
      is less than or equal to the number of caller stack parameters.
    * Use the gap resolver to swizzle parameters and registers to tail calls.

      [heap] Do not require kRingBufferMaxSize samples for estimating compaction speed · c0d310bd
      mlippautz authored 
      There is no need to require kRingbufferMaxSize samples for estimating the
compaction speed, as the number is already quite stable with a single sample
(which may include timings from compacting multiple pages).
