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.
