## Notes:
# This script uses the `emit` function (defined llvmpasses.jl) to emit either
# optimized or unoptimized LLVM IR. Each function is emitted individually and
# `llvm-link` is used to create a single module that can be passed to opt.
# The order in which files are emitted and linked is important since `lit` will
# process the test cases in order.
