Fixed issue with internal real representation, incorrect for non x86-32 architectures. Cleaned up CallExp::toElem, moved implementation to tocall.cpp providing a single procedure to call arbitrary D functions fairly easily.

// idouble

module typeinfo1.ti_idouble;

private import typeinfo1.ti_double;

class TypeInfo_p : TypeInfo_d
{
    char[] toString() { return "idouble"; }
}
