Hans Wennborg a89f546d6a Revert r343058 "[ORC] Add support for multithreaded compiles to LLJIT and LLLazyJIT." ... This doesn't work well in builds configured with LLVM_ENABLE_THREADS=OFF, causing the following assert when running ExecutionEngine/OrcLazy/multiple-compile-threads-basic.ll: lib/ExecutionEngine/Orc/Core.cpp:1748: Expected<llvm::JITEvaluatedSymbol> llvm::orc::lookup(const llvm::orc::JITDylibList &, llvm::orc::SymbolStringPtr): Assertion `ResultMap->size() == 1 && "Unexpected number of results"' failed. > LLJIT and LLLazyJIT can now be constructed with an optional NumCompileThreads > arguments.
