Changed the handling of variadic intrinsics a bit. Removed the -fp80 option and made real be 80bit floats on X86, this is what the D spec really says it should be and fixes a bunch of issues. Changed the handling of parameter attributes to a bit more generalized approach. Added sext/zext attributes for byte/short/ubyte/ushort parameters, fixes #60 . Parameter attribs now properly set for intrinsic calls if necessary. Made the tango.math.Math patch less intrusive. Fixed/added some mini tests.

module tangotests.mem5;

class SC
{
    int* ip;
    this()
    {
        ip = new int;
    }
    ~this()
    {
        delete ip;
    }
    void check()
    {
        assert(ip !is null);
    }
}

void main()
{
    scope sc = new SC;
    sc.check();
}
