This adds the flag IsOverloadCvt which tells CGBulitin to use
the result type and the type of the last operand as the
overloaded types for the LLVM IR intrinsic.

This also adds the flag IsFPConvert, which is needed to avoid
converting the predicate of the operation from svbool_t to
a predicate with fewer lanes, as the LLVM IR intrinsics use
the <vscale x 16 x i1> as the predicate.
