Now that we have a way to mark GlobalValues as local we can use the symbol resolutions that the linker plugin provides as part of lto/thinlto link step to refine the compilers view on what symbols will end up being local. Originally commited as r317374, but reverted in r317395 to update some missed tests. Differential Revision: https://reviews.llvm.org/D35702 llvm-svn: 317408
