Bug 575733 - refactored Scanner/PublicScanner char deduplication
Scanner.<init>() [initial filling of this.charArray_length] took more
time then all the optimizedCurrentTokenSource* methods together.
This was a hotspot when (for example xtext) created a new scanner for
each class.
Now use a single shared deduplicationpool per thread - which only needs
to be initialized once per thread.
+also deduplicate all single Ascii chars.
