Rollup merge of #151071 - gen-openmp-metadata, r=nnethercote Generate openmp metadata LLVM has an openmp-opt pass, which is part of the default O3 pipeline. The pass bails if we don't have a global called openmp, so let's generate it if people enable our experimental offload feature. openmp is a superset of the offload feature, so they share optimizations. In follow-up PRs I'll start verifying that LLVM optimizes Rust the way we want it. r? compiler
