Second review request for 8019553: NPE on illegal l-value for increment and decrement

[A. Sundararajan]

I've to update webrev because of 2 test262 failures. eval("2 = 3") is 
expected to throw ReferenceError rather than SyntaxError ( 
ch11/11.13/11.13.1/11.13.1-1-1.js ). So restored early-error to be 
ReferenceError in Parser.jar. Please review updated webrev.

Please review http://cr.openjdk.java.net/~sundar/8019553/webrev.01/
