Pretenure call new support.
...
When FLAG_pretenure_call_new is on, we emit mementos on new object creation
in full code, and consume the feedback in crankshaft. A key difference in the
generated code for stubs is the allocation of an additional type vector slot for the
CallNew AST node, which simplifies the CallConstructStub and CallFunctionStub
considerably.
Some performance tuning still needs to be addressed, therefore the flag is off at
this moment, though fully functional. The goal is to remove the flag as soon as
possible, which allows much code deletion (yay).

Continued fix for 351257. Reusing the feedback vector is too complex.
...
Attempting to re-use the type feedback vector stored in the
SharedFunctionInfo turns out to be difficult among the various cases.
It will be much easier to do this when deferred type feedback processing
is removed, as is in the works.
Created bug v8:3212 to track re-introducing the optimization of reusing
the type vector on recompile before optimization.
The CL also brings back the type vector on the SharedFunctionInfo.

Improve positions tracking inside the HGraphBuilder.
...
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.

Get rid of the function sorting in for polymorphic calls.
...
The idea of this code was to sort functions according to

even worse by source length) all the time, which is a bad,
arbitrary measure.
