- Get rid of fixing up pointers on the main thread
- Get rid of sweeping on the main thread

Instead:
- Record (and process afterwards) slots in parallel
- Add the pages to the concurrent sweeper as pointers have already been fixed

This reverts commit 6df04b29.

This removes the flag in question. It just duplicates the corresponding
compilation hint in the underlying SharedFunctionInfo object. Now that
the backends should have a SharedFunctionInfo available most of the time
it is safe to use the cannonical predicate.

There were a couple of issues with it:
- interpreter is not supported
- the source position was just accidentally correct for full-codegen
- the eval origin could have been cached

Also fixes a few other places to use AbstractCode.

Modifies Ignition to store code entry addresses in the dispatch table
rather than code objects. This allows the interpreter to avoid
calculating the code entry address from the code object on every
dispatch and provides a ~5-7% performance improvement on Octane with
Ignition.

This change adds ArchOpcode::kArchTailCallAddress to TurboFan to enable
tail call dispatch using these code addresses. It also adds a Dispatch
linkage creator (distinct from the stub linkage type used previously) to
allow targetting a code address target (which will diverge further from
the stub linkage type when we remove the context machine register in
Ignition).

  original commit message:
  In the earlier implementation of GenerateDoubleToObject the context
  is loaded from the parent's frame. rsi is clobbered because it is used
  to store kHoleNan constnat. It is not always safe to peek at
  the parents frame. Bytecode handlers have TypedFrame and the type of
  frame is stored at FP + 1. GenerateDoubleToObject expects context
  to be store at that place. In the current implementation rsi is pushed
  onto the stack and is popped when exiting this function.

To keep track of memory characteristics of a JS program use
GetHeapSpaceStatistics from a combination of
- a GC epilogue callback registered using AddGCEpilogueCallback
- an interrupt registered using RequestInterrupt

Rationale:
The feature is currently broken as those callbacks are (also) executed from
background threads, breaking our implicit contract for only performing callbacks
on the foreground thread. Furhtermore, it's not clear for the embedder whether
these allocations originate in JS, or are required for a GC.

Note:
- The already deprecated non-isolate versions are removed with this CL.

We use the cvttsd2si (float64-to-int32) instruction to avoid that negative numbers get sign extended in the destination register.

@rodolph: Is sign extension also a thing on arm64? I noticed that also on arm64 a float64-to-int64 instruction is used.
