bd5189c25a [String] Grapheme fast paths for punctuation: 5-8x speedup. 
Many strings use non-sub-300 punctuation characters (e.g. unicode
hyphen, CJK quotes, etc). This can cause switching between fast and
slow paths for grapheme breaking. Add in fast-paths for general
punctuation characters and CJK punctuation and symbol characters.

This results in about a 5-8x speedup for heavily (unicode) punctuated
Latiny and CJKy workloads.

075c6e6a04 [benchmark] Add more (off-by-default) StringWalk benchmarks. 
Gyb up StringWalk, to avoid the code explosion. Add in benchmarks for
walking Chinese, Japanese, and Korean text.
