* tests: Upgrade tx log capturing
Instead of overriding the system logger to intercept the logs, we can
now ask solana to return the logs of a tx execution directly.
This speeds up tests a lot because we don't need to hold a global lock
on tx execution anymore!
* tests: Improve token, serum, perp cu test
* benchmark: add a few more operations
This fixes a security issue where bankruptcy related instructions could
be called inside a health region. Now health regions are limited to
compute optimization like when placing multiple orders in one
transaction.
This limitation also makes it impossible to abuse health regions for
flash loans. Use the FlashLoan instructions for that purpose.
Speeds up the linking step, needs way less disk space for test binaries
and executes tests significantly faster.
Test execution went from 35s -> 29s for me and compilation improved a
lot.
