bbc3ebc5e6 StringWalk benchmark: remove global variable access from the loop. 
Global variables are being used as if they are "free black
holes". They might be even more expensive than actually calling
blackHole. But the right thing to do is use local variables and pass
them into a black hole at the end of computation.

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.
