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.

This reverts commit 0229dd0626b2538c78ebbd2b1bd44c31fbf1cdec.
This introduces two test failures on s390x.

This patch adds possibility to keep not only DwarfStringPoolEntry, but also
pointer to it. The DwarfStringPoolEntryRef keeps reference to the string map entry.
String map keeps string data and corresponding DwarfStringPoolEntry
info. Not all string map entries may be included into the result,
and then not all string entries should have DwarfStringPoolEntry
info. Currently StringMap keeps DwarfStringPoolEntry for all entries.
It leads to extra memory usage. This patch allows to keep
DwarfStringPoolEntry info only for entries which really need it.
[reland] : make msan happy.
