Improve performance for LIKE patterns involving %

[martint]

When the pattern contains only literals and %, use substring
search for each of the tokens, via an implementation of the
FJS algorithm: https://cgjennings.ca/articles/fjs/

Benchmark results follow:

• dynamicXXX measures the end-to-end performance of compiling
  the matcher and calling it.
• matchXXX measures the performance of the match call after
  the matcher has been compiled
• xxxNonOptimized vs xxxOptimized measures the performance
  when LikeMatcher is constructed with optimize = true/false
