[LTO][ThinLTO] Use the linker resolutions to mark global values as dso_local. 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

; Bitcode compatibility test for dso_local flag in thin-lto summaries.
; Checks that older bitcode summaries without the dso_local op are still
; properly parsed and don't set GlobalValues as dso_local.
[Bitcode] Update CHECK-DAG usage in tests This patch adjusts tests not to depend on deprecated FileCheck behavior that permits overlapping matches within a block of `CHECK-DAG` directives: 1. `thinlto-function-summary-originalnames.ll`: The directive with the pattern `<COMBINED` is surely intended to match `<COMBINED ` (note the trailing space), but it instead matches `<COMBINED_GLOBALVAR_INIT_REFS`, for which there is a separate directive. With the deprecated behavior, both directives match the latter text and neither match the former text. I've adjusted the former directive so it matches only the former text. 2. `thinlto-summary-local-5.0.ll`: Two directives have identical patterns when they were clearly meant to have different patterns. 3. `upgrade-pointer-address-space.ll`: There are three identical directives but only two occurrences of the matching text. With the deprecated behavior, they always match exactly the same text, so the behavior can't have been useful. I removed one of the directives and converted the other two from `CHECK-DAG` to `CHECK`.
