What is the current behavior?

Resolves: #914

What is the new behavior?

• Saturates the gas taken from the stack to MAX_U128 so that, if the gas is passed with a very big value, the execution doesn't throw an error here. The actual gas passed to the call will depend on the min(gas_left, gas_param), and since gas_left is a u128, it's safe to saturate

Does this introduce a breaking change?

• Yes
• No
