This patch is a reland of 74e4f778cf16cbf7163b5c6de6027a43f5e9169f and f83347b0bedb22ea676861c8e4e2ed9c31371ade with the removed 50 trick back. The magic number 50 was removed in D134942, as a behavior change for performance reason. While it reduces the number of SLocEntry, it increases the usage of SourceLocation address space usage, which is critical for compiling large TU. This fixes a regression caused in D134942 -- clang failed to compile one of our internal files, complaining the file is too large to process because clang runs out of source location space (we spend 40% more address space!)
