I've updated syntex, aster, and quasi, but I'm unfortunately still blocked on rust-lang/rust#30713 being fixed, which is breaking the rand crate on nightly.

@erickt thanks for responding; glad to know it's not something on my end. I'll keep an eye on that issue. Thanks!

bigint: allow Sub to work in-place on the RHS
388a313 
A new Fibonacci benchmark demonstrates the improvement by using both
addition and subtraction in each iteration of the loop, like serde-rs#200.

Before:

    test fib2_100          ... bench:       4,558 ns/iter (+/- 3,357)
    test fib2_1000         ... bench:      62,575 ns/iter (+/- 5,200)
    test fib2_10000        ... bench:   2,898,425 ns/iter (+/- 207,973)

After:

    test fib2_100          ... bench:       1,973 ns/iter (+/- 102)
    test fib2_1000         ... bench:      41,203 ns/iter (+/- 947)
    test fib2_10000        ... bench:   2,544,272 ns/iter (+/- 45,183)
