Option for Enforcing Intrinsic Expansion

Currently intrinsic is disabled under MIN_OPT while being enabled under OPT.
There is no way to enforce intrinsic expansion where non-intrinsic (call) path is not yet implemented.
This adds an optional output boolean argument to getIntrinsicID that tells JIT whether to enforce intrinsic expansion.
If JIT cannot expand intrinsic for such case, fatal error occurs.
There is no functional change the argument is default to false.
