[llvm-cov] Add a cl::opt to control the number of threads
When an output directory is specified, llvm-cov spawns some threads to
speed up the process of writing out file reports. Add an option which
allows users to control how many threads llvm-cov uses.
A CommandGuide.rst update + test is included.
