Teresa Johnson 2209e677a1 [ThinLTO] Launch importing backends in parallel threads from gold plugin ...

Summary:
Launch ThinLTO backends (LTO and codegen pipelines with importing) in
parallel using a ThreadPool, after creating the combined index.
The number of threads is controlled by the existing -jobs gold plugin
option, or the hardware concurrency if not specified.

The old behavior of exiting after creating the combined index can be
invoked via a new thinlto-index-only plugin option.

This commit involves just the ThinLTO-specific pieces of D15390, the NFC
and other restructuring pieces were committed independently:
  r262677: Add hardware_concurrency interface to llvm::thread (NFC)
  r262719: Change split code gen to use ThreadPool
  r262721: Refactor gold-plugin codegen to prepare for ThinLTO threads (NFC)
