dc87d51f70 Changed Boyer-Moore's bad-char table code: 
- Reduce it to half size if the pattern is ASCII, saving on initialization
- If pattern is ASCII and subject is not, any non-ASCII char can cause a
  full pattern-length shift, even if we haven't indexed the entire pattern.
- Use memset to initialize buffer in the common case where the pattern is
  shorter than the max significant suffix limit.

c04546333a * Special case for last char in BM-match 
* Patch from Erik Corry to separate BM-algoritm into special case
  functions. Also changes condition for bailing out of simple search.
* Added simple search with no bailout for very short patterns.

and mutation (pushes and pops) go through the virtual frame.

  strings with an ascii/two-byte representation, of which there is
  four, and flat sequential ascii/two-byte string.
