[ThinLTO] Disable importing and other cross-module optis at -O0 Summary: There is no point to importing at -O0, since we won't inline. We should also disable other cross-module optimizations. (Plan to backport this fix to the 3.9 branch to fix PR30774) Reviewers: pcc Subscribers: johanengelen, mehdi_amini Differential Revision: https://reviews.llvm.org/D25918 llvm-svn: 285648

llvm-lto2: Move the LTO::run() action behind a subcommand. Move LTO::run() to a "run" subcommand so that we can introduce new subcommands for testing different parts of the LTO implementation. This doesn't use llvm::cl subcommands because it doesn't appear to be currently possible to pass an argument not associated with a subcommand to a subcommand (e.g. -lto-use-new-pm, -mcpu=yonah).

[LTO] Make processing of combined module more consistent Summary: 1. Use stream 0 only for combined module. Previously if combined module was not processes ThinLTO used the stream for own output. However small changes in input, could trigger combined module and shuffle outputs making life of llvm::LTO harder. 2. Always process combined module and write output to stream 0. Processing empty combined module is cheap and allows llvm::LTO users to avoid implementing processing which is already done in llvm::LTO.

[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
