Another upstreaming of C API extensions we have in Julia/LLVM.jl. Although [we went](https://github.com/maleadt/LLVM.jl/pull/431) with a string-based API there, here I'm proposing something that's similar to existing metadata/attribute APIs: - explicit functions to map syncscope names to IDs, and back - `LLVM*SyncScope` versions of builder APIs that already take a `SingleThread` argument: atomic rmw, atomic xchg, fence - `LLVMGetAtomicSyncScopeID` and `LLVMSetAtomicSyncScopeID` for other atomic instructions - testing through `llvm-c-test`'s `--echo` functionality
