* Make regalloc2 `#![no_std]` This crate doesn't require any features from the standard library, so it can be made `no_std` to allow it to be used in environments that can't use the Rust standard library. This PR mainly performs the following mechanical changes: - `std::collections` is replaced with `alloc::collections`. - `std::*` is replaced with `core::*`. - `Vec`, `vec!`, `format!` and `ToString` are imported when needed since they are no longer in the prelude. - `HashSet` and `HashMap` are taken from the `hashbrown` crate, which is the same implementation that the standard library uses. - `FxHashSet` and `FxHashMap` are typedefs in `lib.rs` that are based on the `hashbrown` types. The only functional change is that `RegAllocError` no longer implements the `Error` trait since that is not available in `core`. Dependencies were adjusted to not require `std` and this is tested in CI by building against the `thumbv6m-none-eabi` target that doesn't have `std`. * Add the Error trait impl back under a "std" feature
