This restricts turbofan to turbofan-supported subset for the shipping
configuration ("use asm" and features unsupported by Crankshaft).

Without this, we compile with Turbofan even when there is
try-catch-finally as long as the function is "use asm" or
it contains a feature unsupported by crankshaft but supported
by turbofan (e.g., 'with' statement).
