[PATCH] D26006: Further reduce the number of allocators

[Rafael Avila de Espindola via llvm-commits]

It changes where things are allocated from. Right now every file has 3 allocators for the sections. With the patch all of them use a common allocator, so stuff from the same file is closer together. We also don't fragment memory as much.
