patch-jit-llvm-version-3.15.patch

The configure script hard-codes the LLVM version for JIT compilation.

This patch overrides the hard-coded version to match our toolchain's LLVM version.

We can't upstream this per say. I guess the next step here would be to allow the LLVM version for the JIT to be configured?

It looks like our version matches in 3.15 now though?

@brandtbucher do you have thoughts on this?

@jjhelmus should we delete this patch now that the version matches or retain it to make a future bump easy?
