      [cpu-profiler] Add a new profiling mode with a more detailed call tree. · ecae80cd
      Peter Marshall authored 
      The current profiling mode (called kLeafNodeLineNumbers in this CL)
produces a tree, with each node representing a stack frame that is seen
in one or more samples taken during profiling. These nodes refer to a
particular function in a stack trace, but not to a particular line or
callsite within that function.

This CL adds a new more (called kCallerLineNumbers) which produces a
different profile tree, where each stack trace seen during profiling,
including the line number, has a unique path in the tree.

The profile tree was previously keyed on CodeEntry*. Now it is keyed on
the pair of CodeEntry* and line_number, meaning it has distinct nodes
for those combinations which exist, and each distinct stack trace that
was sampled is represented in the tree.

For optimized code where we have inline frames, there are no line
numbers for the inline frames in the stack trace, causing duplicate
branches in the tree with kNoLineNumberInfo as the reported line number.
This will be addressed in follow-ups.

      [api] Add a dedicated UnboundModuleScript type · 8ec92f51
      jgruber authored 
      Module and script SharedFunctionInfos can't be used interchangeably
(e.g.: it should not be possible to bind a Module's SFI to a Context).

The dedicated type disambiguates the two.

This also adds an overload for CreateCodeCache which takes an unbound
module script instead of an unbound script. Both are just a SFI
underneath, so their behavior is identical.

      [debug] add ability to do side-effect-free call to NewInstance · 4b52f964
      Erik Luo authored 
      Creating a new instance from a v8::Function will invoke its
constructor. If it is an API callback that has not been marked as
kHasNoSideEffect, this CL introduces a way to invoke it without
throwing.

Calls within the constructor are still checked for side effects.

      [api] Add Module::GetUnboundScript() · 2d3f6f91
      jgruber authored 
      This method is intended for use by code caching as follows:

1. The module is compiled (and perhaps instantiated).
2. The embedder fetches and stores the module's unbound script (i.e.
   the shared function info).
3. Module evaluation, maybe triggering lazy compilation.
4. Generated code for the module (which hangs off the shared function
   info) is inserted into the code cache.

Subsequent module loads can load from the code cache prior to
evaluation.

      [api] Split isolate allocation and initialization · 5c9b30ae
      Andreas Haas authored 
      At the moment, the isolate is allocated and initialized in a single
step. This has the downside that the platform cannot register the
isolate before the isolate gets initialized, and therefore the platform
is not available for the isolate during initialization. With this CL we
register the uninitialized isolate on the platform and initialize the
isolate after that.

This change is needed to allow the creation of task runners already
during the initialization of the isolate.
