Cargo.toml: Tame {on=>in} Rust Changed to match README.md. This makes more sense too.

Introduce CARGO_BUILD_FLAGS This is intended to permit passing `--release`, since dev builds are terribly slow (e.g. 6s -> 0.2s). See README.md for more information.

[DEV-7081] Add options to tameld We want to add an option to set the output file to the linker so we do not need to redirect output to awk any longer. This also adds integration tests for tameld.

TAMER: Arena-based string interner Contrary to what I said previously, this replaces the previous implementation with an arena-backed internment system. The motivation for this change was investigating how Rustc performed its string interning, and why they chose to associate integer identifiers with symbols. The intent was originally to use Rustc's arena allocator directly, but that create pulled in far too many dependencies and depended on nightly Rust. Bumpalo provides a very similar implementation to Rustc's DroplessArena, so I went with that instead. Rustc also relies on a global, singleton interner. I do not do that here. Instead, the returned Symbol carries a lifetime of the underlying arena, as well as a pointer to the interned string. Now that this is put to rest, it's time to move on.

tamer::sym: FNV => Fx Hash For strings of any notable length, Fx Hash outperforms FNV. Rustc also moved to this hash function and noticed performance improvements. Fortunately, as was accounted for in the design, this was a trivial switch. Here are some benchmarks to back up that claim: test hash_set::fnv::with_all_new_1000 ... bench: 133,096 ns/iter (+/- 1,430) test hash_set::fnv::with_all_new_1000_with_capacity ... bench: 82,591 ns/iter (+/- 592) test hash_set::fnv::with_all_new_rc_str_1000_baseline ... bench: 162,073 ns/iter (+/- 1,277) test hash_set::fnv::with_one_new_1000 ... bench: 37,334 ns/iter (+/- 256) test hash_set::fnv::with_one_new_rc_str_1000_baseline ... bench: 18,263 ns/iter (+/- 261) test hash_set::fx::with_all_new_1000 ... bench: 85,217 ns/iter (+/- 1,111) test hash_set::fx::with_all_new_1000_with_capacity ... bench: 59,383 ns/iter (+/- 752) test hash_set::fx::with_all_new_rc_str_1000_baseline ... bench: 98,802 ns/iter (+/- 1,117) test hash_set::fx::with_one_new_1000 ... bench: 42,484 ns/iter (+/- 1,239) test hash_set::fx::with_one_new_rc_str_1000_baseline ... bench: 15,000 ns/iter (+/- 233) test hash_set::with_all_new_1000 ... bench: 137,645 ns/iter (+/- 1,186) test hash_set::with_all_new_rc_str_1000_baseline ... bench: 163,129 ns/iter (+/- 1,725) test hash_set::with_one_new_1000 ... bench: 59,051 ns/iter (+/- 1,202) test hash_set::with_one_new_rc_str_1000_baseline ... bench: 37,986 ns/iter (+/- 771)

TAMER: Initial string interning abstraction This is missing two key things that I'll add shortly: a HashMap-based one for use in the ASG for node mapping, and an entry-based system for manipulations. This has been a nice start for exploring various aspects of Rust development, as well as conventions that I'd like to implement. In particular: - Robust documentation intended to guide people through learning the necessary material about the compiler, as well as related work to rationalize design decisions; - Benchmarks; - TDD; - And just getting used to Rust in general. I've beat this one to death, so I'll commit this and make smaller changes going forward to show how easily it can evolve. (This module was originally named `intern` but this commit and those that follow rewrote it to `sym`.)
