[lld] r283787 - [LTO/Thin] Make the number of threads to run in the BE configurable.

[Peter Collingbourne via llvm-commits]

The gold plugin exposes --plugin-opt=jobs=N (which controls the number of
ThinLTO jobs) and --plugin-opt=lto-partitions=N (which controls the number
of parallel LTO codegen partitions). I don't think we want to expose any
flags with names based on plugin-opt, but it does make sense to me to use
similar names.

What I would suggest is that we name our flags --thinlto-jobs and
--lto-partitions.
