Bug 117593 – Avoid duplicate isInt32() / isUInt32() checks in JSDOMBindings

• Component: Bindings
• Status: RESOLVED FIXED

[Chris Dumez]

In JSDOMBindings.cpp, the following pattern is used several times:
if (value.isInt32())
    return value.toInt32(exec);

This would be more efficiently written as:
if (value.isInt32())
    return value.asInt32();

The issue is that JSValue::toInt32() also calls value.isInt32() internally as well and returns value.asInt32() if it is.
We should therefore call asInt32() directly since we already know the value is an int32.
