Details

Bug 621961 will inline some common builtins, but to make Math.abs(x) as fast as abs(x) we still have to optimize the getgname "Math"

Talked about this with bhackett on IRC, we can reuse the singleton JSObject* introduced by 621961. getgname can then push a frame entry with constant value (and not generate any code)
