[code-reflection] RFR: Bytecode round 10 [v3]

[Adam Sotona]

> This time I focused on the roundtrip stabilizations, namely:
> - BytecodeLift: injected blocks do not pass the stack through block params
> - Avoided redundant slot loads and stores for parameters of blocks with just a single predecessor
> - SlotSSA calculates join point block argument types from the consuming slot load ops (instead of the slot store ops)
> - TestSmallCorpus now performs triple round stability verification and actual numbers are: >99% of methods is stable, no exceptions, no verification errors
> 
> Remaining instability of ~130 methods is related to nested try blocks.
> 
> Please review.
> 
> Thanks,
> Adam
