Simplify HInvokeStatic code generation.

HPushArgument is not needed for now (but might be when we start
optimizing). Also, calling convention for 64bits backend will
require to know more about the argument than the argument's
index. Therefore currently let HInvokeStatic setup the arguments,
which is possible because arguments of a calls are virtual registers
and not instructions.
