[ThinLTO] Thin link efficiency improvement: don't re-export globals (NFC) Summary: We were reinvoking exportGlobalInModule numerous times redundantly. No need to re-export globals referenced by a global that was already imported from its module. This resulted in a large speedup in the thin link for a big application, particularly when importing aggressiveness was cranked up.

Make GlobalValues with non-default visibilility dso_local. This is similar to r322317, but for visibility. It is not as neat because we have to special case extern_weak. The idea is the same as the previous change, make the transition to explicit dso_local easier for the frontends. With this they only have to add dso_local to symbols where we need some external information to decide if it is dso_local (like it being part of an ELF executable). llvm-svn: 322806

Reland "Change the X86 datalayout to add three address spaces for 32 bit signed, 32 bit unsigned, and 64 bit pointers." This reverts 57076d3199fc2b0af4a3736b7749dd5462cacda5.
