Summary of Changes

Feature Gate Issue: https://github.com/anza-xyz/feature-gate-tracker/issues/78

[mergify]

The Firedancer team maintains a line-for-line reimplementation of the
native programs, and until native programs are moved to BPF, those
implementations must exactly match their Agave counterparts.
If this PR represents a change to a native program implementation (not
tests), please include a reviewer from the Firedancer team. And please
keep refactors to a minimum.

Does truncate also increase the account size? If so, the name might be misleading.

[Lichtso]

Yes, Truncate can also increase the size and it is common for file systems to only have one function for both directions: https://www.man7.org/linux/man-pages/man2/truncate.2.html

[LucasSte]

I see linux use the same naming, but we can improve our designation and call it resize.
Truncate means shortening: https://www.collinsdictionary.com/dictionary/english/truncate

[Lichtso]

Yep, also still have to write a test for the new instruction.
