      Add CompileInfo::GetDebugName() · 53ac9fe8
      rmcilroy authored 
      Replaces all instances of the code which computed the debug
name of a stub or function with calls to CompileInfo::GetDebugName instead.

Also:
  - Removes useless parameter on CodeStub::GetMajorName
  - Removes FakeStubForTesting since it is no longer required
  - Adds CompileInfo::ShouldEnsureSpaceForLazyDeopt() to replace unclear calls to IsStub().

      Remove the dependency of Zone on Isolate · c7b09aac
      danno authored 
      Along the way:
- Thread isolate parameter explicitly through code that used to
  rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
  affected code
- Change Hydrogen New<> instruction templates to automatically
  pass isolate

      Improve positions tracking inside the HGraphBuilder. · 8f170a66
      vegorov@chromium.org authored 
      Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.
