[PATCH] D32315: Introduce a new DWARFContext::getInliningInfoForAddress API to expose pointers to strings stored in DWARF file.

With the current getInliningInfoForAddress API, the FileName and FunctioName are both stored as std::string. This is not efficient for batch symbolization job as it incurs too much redundant string copy operation. This patch introduces a new API to allow user to specify customized inserter so that user can build a container that directly reference strings in the DWARF file to avoid string copy, which will speeds up batch symbolization by 2X.
