Update codegen to (hopefully) work correctly with newer LLVM trunk, where there's no longer a Fast flag. (It has been replaced by an optimization level) Untested because I haven't compiled that recent an LLVM yet :).

module typeinfos2;

import
typeinfo2.ti_AC,
typeinfo2.ti_Adouble,
typeinfo2.ti_Afloat,
typeinfo2.ti_Ag,
typeinfo2.ti_Aint,
typeinfo2.ti_Along,
typeinfo2.ti_Areal,
typeinfo2.ti_Ashort,
typeinfo2.ti_C;
