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 typeinfo13;

void main()
{
    float[long] aa;
    auto ti = typeid(typeof(aa));
    assert(ti.toString() == "float[long]");
    assert(ti.next() is typeid(float));
    assert(ti.tsize() == size_t.sizeof);
    auto aati = cast(TypeInfo_AssociativeArray)ti;
    assert(aati.value is typeid(float));
    assert(aati.key is typeid(long));
