[llvm-cov] Don't spawn a thread unless ThreadCount > 1 Initializing a ThreadPool with ThreadCount = 1 spawns a thread even though we don't need to. This is at least slower than it needs to be, and at worst may somehow be exacerbating PR30735 (llvm-cov times out on ARM bots). As a follow-up, I'll try to add logic to llvm::ThreadPool to avoid spawning a thread when ThreadCount = 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@284621 91177308-0d34-0410-b5e6-96231b3b80d8
