Remove an old workaround that was kept around for ABI-compatibility on x86-64 between different LLVM versions. This means LLVM r67588 is required if you want to compile for x86-64, otherwise the backend will assert when you try to return e.g. struct { int i; char c; } from a function. (In particular, this is no longer compatible with LLVM 2.5) It also means that any code returning small structs on x86-64 will probably need to be recompiled in order to be linkable to code compiled with this change.

void ints()
{
    int[3] a = [1,2,3];
    int[3] b = [2,3,4];
    int[3] c = [2,5,0];
    {assert(a < b);}
    {assert(b > a);}
    {assert(a < c);}
    {assert(c > a);}
    {assert(b < c);}
    {assert(c > b);}
}

    ints();
