gas: Implement && and || for if statements

Now if statements are complete! The function
%gas_assembly_generator_compile_condition% is generic and will be used
for any other flow-control statment. The only requirement to it work is
having two labels: One to jump when the condition is true, and another
one when the condition is false.
