Introduce a simple binary that can run arbitrary input against any of
the available implementations (musl, MPFR, our libm). This provides an
easy way to check results, or run specific cases against a debugger.
Examples:
$ cargo run -p util -- eval libm pow 1.6 2.4
3.089498284311124
$ cargo run -p util -- eval mpfr pow 1.6 2.4
3.089498284311124
$ cargo run -p util -- eval musl tgamma 1.2344597839132
0.9097442657960874
$ cargo run -p util -- eval mpfr tgamma 1.2344597839132
0.9097442657960874
$ cargo run -p util -- eval libm tgamma 1.2344597839132
0.9097442657960871
$ cargo run -p util -- eval musl sincos 3.1415926535
