This patch creates DWARFLinkerBase library, places DWARFLinker code into
DWARFLinker\Classic, places DWARFLinkerParallel into DWARFLinker\Parallel.
updates BOLT to use new library. This patch is NFC.
This patch is extracted from D96035, it adds support for the existing
DWARFLinker functionality. What is not supported yet:
1. Types deduplication(--odr mode).
2. Modules deduplication.
3. Generation of index tables.
Reland2: temporarily disabled call to "--linker llvm" for tls-variable.test
and location-expression.test as it does not work properly on bigendian
architecture.

PerThreadBumpPtrAllocator allows separating allocations by thread id.
That makes allocations race free. It is possible because
ThreadPoolExecutor class creates threads, keeps them until
the destructor of ThreadPoolExecutor is called, and assigns ids
to the threads. Thus PerThreadBumpPtrAllocator should be used with only
threads created by ThreadPoolExecutor. This allocator is useful when
thread safe BumpPtrAllocator is needed.
