I think the main problem is the fact that the SPIR format is fixed to
the IR produced by certain LLVM versions. So, if later LLVM versions
have changes in the IR output, it might not produce valid SPIR
binaries anymore.

SPIR 1.2 is fixed to LLVM 3.2 IR and SPIR 2.0 to LLVM 3.4.

However, if there are other non-SPIR-specific features in that branch,
I hope Someone breaks them up in smaller patches so they get reviewed and
