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.

f45bddcaa6 benchmarks: Convert the GlobalClass benchmark to a SILOptimizer test 
The purpose of the benchmark was to check a very specific ARC optimization, which is better tested with a lit test.
Beside that, the benchmark was broken anyway.

e56bf42acb Update generate_harness.py templates 
These templates had gotten slightly out of date through
manual edits. These changes make it so that running
generate_harness.py actually generates the desired files.

Changes to the non-template files are a result of the script's
alphabetization.
