233ea0eef8 Reland: Simplify and compact transitions storage 
Original issue: https://codereview.chromium.org/980573002/

Simple transitions are now stored in a map's "transitions" field (as a WeakCell wrapping the target map); full TransitionArrays are used when that's not sufficient.
To encapsulate these storage format implementation details, functions for manipulating and querying transitions have been refactored to be static functions on the TransitionArray class, and take maps as inputs.

0e3b5386ae Scanner / Unicode decoding: use size_t instead of unsigned. 
size_t is the correct data type for this purpose. Our APIs (in particular
ExternalSourceStream::GetMoreData) are already using it, and there were some
static_casts to convert between them.

This CL doesn't intend to fix all of V8, just the minimal sense-making part
around scanner character streams.

269c46ee80 Simplify synthetic roots creation in heap snapshot 
The synthetic roots exist in every snapshot and there are no actual objects corresponding to them (there was attempt to create some virtual objects to reuse existing snapshot builder but it just complicated the things).

Previously synthetic root wouldn't have been added if it was empty. Current implementation always adds all synthetic roots in the snapshot no matter if they are empty or not.
