7256690364 Add shadow frame link stack for trace recorder. 
Simplifies snapshots. Prerequisite for pre-call snapshots.
Increases consistency for fast function calls, too.

67ca399a30 Compress snapshots using a simple, extensible 1D-compression. 
Typically reduces storage overhead for snapshot maps by 60%.
The extensible format is a prerequisite for the next redesign steps:
Eliminate IR_FRAME and implement return-to-lower-frame.

99d153bef9 Improve alias analysis of upvalues using a disambiguation hash value. 
All upvalue objects hold a disambiguation hash value now.
It's built from the parent prototype and the slot number.
Different hash values imply the upvalues cannot alias.
Same hash values don't imply anything (collision or different closures).
Upvalue disambiguation makes use of a reduced hash due to IR contraints.
