Make sure that if anyone passes a name by accident for the isSigned
parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler). Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.
