* Case insensitive regexp character class compilation has bad performance

* behavior up to Duktape 2.1.0. In Duktape 2.2.0 there's a significant
|
|
* improvement but case insensitive regexps are still much slower than they
|
|
* could be. Basic test for case insensitive regexp character class worst
|
|
* case behavior.
