Upgrades Rust to 1.72.0 & nightly-2023-08-25 (#32961) * allow pedantic invalid cast lint * allow lint with false-positive triggered by `test-case` crate * nightly `fmt` correction * adapt to rust layout changes * remove dubious test * Use transmute instead of pointer cast and de/ref when check_aligned is false. * Renames clippy::integer_arithmetic to clippy::arithmetic_side_effects. * bump rust nightly to 2023-08-25 * Upgrades Rust to 1.72.0 --------- Co-authored-by: Trent Nelson <trent@solana.com> 2023-09-01 00:26:13 -07:00			`#![deny(clippy::arithmetic_side_effects)]`
Moves AlignedMemory from solana_rbpf into a new crate: memory-managment. (#28079) * Moves AlignedMemory from solana_rbpf into a new crate: memory-managment. * Makes cargo clippy happy. * deny clippy::integer_arithmetic * Makes write_unchecked() take a generic parameter. * Restricts AlignedMemory::write_unchecked() to Pod types. * Adds DynamicLayoutArray. * Moves is_memory_aligned() into crate root. 2022-10-04 23:39:55 -07:00			`pub mod aligned_memory;`
