[PATCH] D78950: Adds LRU caching of compile units in DWARFContext.

[Hyoun Kyu Cho via Phabricator via llvm-commits]

Reflected the discussion we've had so far. Made minimum change to the lower level API (DWARFContext, DWARFDebugLine, and DWARFUnit) to make it possible for the high level API and symbolization tool to implement caching. Added a higher level API (DWARFCachedDIContext) that implements DIContext with LRU caching so that llvm-symbolizer could benefit from the caching without code change. It is also a step toward decoupling DWARFContext from DIContext in the future which would be desirable for other use of DWARFContext (e.g. LLDB). Finally, added a unit test for the LRU logic.
