7542b540e4 Bug 1535154 - Merge PrivateScriptData scopes/objects/bigints arrays into a single array of GC things. r=tcampbell,jonco 
Once the other data is moved out of PrivateScriptData, this GC-thing array will be stored
at a fixed offset. At that point we can simplify PrivateScriptData and get fast indexing
into this array, important for the Baseline Interpreter.

22445824ad Bug 1537909 - Optimise external read barriers r=sfink? 
Add a special path for the external read barrier API where we inline most of the checks and then always perform the barrier if we call into the engine.  This also skips dispatching on trace kind since we know the barrier tracer is always a GCMarker.

This is kind of hacky and I'm not sure how much it gains us (it's difficult to tell in profiles where GC may occur at different times).  What do you think?

b425876903 Bug 1306008 - Give JS::Heap<T> pointer wrappers a pre-barrier r=sfink 
This adds a pre write barrier to Heap<T> so that these can be uses as non-roots in the heap without breaking our snapshot at the beginning invariant if they are written to during an incremental GC. This makes it harder to misuse and allows us to take out manual barriers in at least one place.

3d03b347e6 Bug 1479900 - Part 2: Refactor GC relocation to use a reserved flag. r=sfink 
This refactors gc::Cell derived types to start with a uintptr_t-sized
field with the low bits reserved for the GC and uses these bits for
relocation mechanism.

- JSString now stores flags in a uintptr_t. On 32-bit platforms, a
  second field is used to hold length.
- Redefine JSString flag bit positions to avoid cell reserved bits.
- Forwarded Cells are now indicated by a reserved flag instead of a
  magic invalid-pointer-like value.
- gc::RelocationOverlay now extends gc::Cell
- Update js::Symbol, js::Scope and js::BigInt fields to be compatible.

1e9c395548 Bug 1466168: Remove mozilla::Forward in favor of std::forward. r=froydnj 
Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:

  s/mozilla::Forward/std::forward/
  s/Forward</std::forward</

The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)
