+ REGRESSION (r174226): Header on huffingtonpost.com is too large
+ https://bugs.webkit.org/show_bug.cgi?id=140306
+
+ Reviewed by Geoffrey Garen.
+
+ Updated js/arguments-iterator to test changing argument to array values.
+ Removed tests that changed arguments to a string and an object as they were
+ bogus and didn't test what the appeared to test.
+ for .. of works on iterable objects only.
+
+ Added new regression test, js/regress-140306.

+ BytecodeGenerator::willResolveToArguments() is used to check to see if we can use the
+ arguments register or whether we need to resolve "arguments". If the arguments have
+ been captured, then they are stored in the lexical environment and the arguments
+ register is not used.
+ Changed BytecodeGenerator::willResolveToArguments() to also check to see if the arguments
+ register is captured. Renamed the function to willResolveToArgumentsRegister() to
+ better indicate what we are checking.
