Optimize compute units via compiler flags

[armaniferrante]

The following Cargo.toml settings have been shown to reduce compute units

[profile.release]
lto = "fat"
codegen-units = 1

[profile.release.build-override]
opt-level = 3
incremental = false
codegen-units = 1

Example here project-serum/serum-dex#159

@armaniferrante is this still relevant? If so I don't understand why this isn't the default setting. Is there a hidden tradeoff?

Slower compile times is the only one I'm aware of.
