Andrew Gallant 203c509df9 Add SIMD accelerated multiple pattern search.
This uses the "Teddy" algorithm, as learned from the Hyperscan regular
expression library: https://01.org/hyperscan

This support optional, subject to the following:

1. A nightly compiler.
2. Enabling the `simd-accel` feature.
3. Adding `RUSTFLAGS="-C target-feature=+ssse3"` when compiling.
