      [heap] Remove independent handles · 667555c6
      Michael Lippautz authored 
      Removes the handling of the flag independent. The flag will be removed in a followup.

The patch changes handling of V8::PersistentBase that are set to Weak:
- The Scavenger ignores the flag independent.
- The Scavenger keeps alive anything that is marked as Active.
- The Scavenger is free to drop weak handles of non-Active object if they 
  are otherwise dead.

Active:
- Any JSObject will always be marked Active.
- Any JSApiObject will be marked Active if it has been modified (=has elements, properties, etc.)

      [builtins] Introduce proper base::ieee754::log. · d0c7775d
      bmeurer authored 
      This switches Math.log to use an fdlibm based version of log, imported
as base::ieee754::log, and use that consistently everywhere, i.e. change
the Float64Log TurboFan operators on Intel to use the C++ implementation
as well (same for Crankshaft).

      Eliminate zero count allocations from profile · 3184aff9
      mattloring authored 
      If no objects allocated at a location are live when a profile is
collected we report a zero count sample. This is confusing to those
looking at the profiles and will leak memory.

We now delete allocations once the number of sampled live objects for
that location reaches zero.

      Prepare StackFrame hierarchy & iterators for WASM · 08454486
      clemensh authored 
      This particularly changes the StackTraceFrameIterator such that is not
only returs JavaScriptFrames, but also WasmFrames. Because of that,
some methods (Summarize, function, receiver) were pulled up to the
StandardFrame, with specializations in JavaScriptFrame and WasmFrame.

      Gracefully handle unloaded scripts · 607143d4
      mattloring authored 
      If a script is unloaded between the collection of an allocation and the
tranlation of an allocation profile, the profiler will segfault. With
this change, we report unloaded scripts as having no line number,column
number, or name.

      Unsampling for the sampling heap profiler · 50537bad
      mattloring authored 
      Implements poisson unsampling. A poisson process is used to determine
which samples to collect based on a sample rate. Unsampling will
approximate the true number of allocations at each site taking into
account that smaller allocations are less likley to be sampled.

This work was originally being done in the agent that
consumes profiles but it is more efficient to do it here
and individual consumers of the API should not have to
worry about the mathematical details of the sampling
process.

      Allocation sampling for paged/large object spaces · f3cdf8a9
      mattloring authored 
      This change expands allocation sampling to include old, map, code, and large object spaces. This involved refactoring much of the observation logic out of NewSpace into Space and overriding as needed in sub-classes.

Additionally, the sampling heap profiler now maintains a pair of heap observers. One observer is used for observing new space and resetting the inline allocation limit to be periodically notified of allocations. The other observes allocation across the other spaces where there is no additional work required to observe allocations.

Tests have been updated to ensure that allocations are observed correctly for Paged and LargeObject spaces.
