  [JSC] Add ClassSetCharacter syntax tests for RegExp V flag and fix issues found

Reviewed by Mark Lam.

Added ClassCharacterSet tests.

Factored out the syntax checking of class set character from parseClassSet() to
consumeAndCheckIfValidClassSetCharacter() and used it in its original location as well as
parseClassStringDisjunction().  Added an additional check for the reserved double punctuators.
Also added explicit handling of '-' in parseClassStringDisjunction() since it is an
additional syntax error, where it is needed for constructing ranges in parseClassSet().
