[PATCH] D26006: Further reduce the number of allocators

[Rui Ueyama via llvm-commits]

ruiu added a comment.

I don't think I fully understand why this can make things faster. This patch replaces

  llvm::SpecificBumpPtrAllocator<[derived class of InputSection]>

with

  std::unique_ptr<InputSection>,

so the number of allocations and the number of deallocation (which should be zero if _exit is called) don't change, IIUC.
