[ThinLTO] Fix ThinLTOCodegenerator to export llvm.used symbols

2019-04-17T17:38:09+00:00

Summary:
Reapply r357931 with fixes to ThinLTO testcases and llvm-lto tool.

ThinLTOCodeGenerator currently does not preserve llvm.used symbols and
it can internalize them. In order to pass the necessary information to the
legacy ThinLTOCodeGenerator, the input to the code generator is
rewritten to be based on lto::InputFile.

Now ThinLTO using the legacy LTO API will requires data layout in
Module.

"internalize" thinlto action in llvm-lto is updated to run both
"promote" and "internalize" with the same configuration as
ThinLTOCodeGenerator. The old "promote" + "internalize" option does not
produce the same output as ThinLTOCodeGenerator.

Move summary creation out of llvm-as into opt

2016-04-12T21:35:18+00:00

Summary:
Let keep llvm-as "dumb": it converts textual IR to bitcode. This
commit removes the dependency from llvm-as to libLLVMAnalysis.
We'll add back summary in llvm-as if we get to a textual
representation for it at some point. In the meantime, opt seems
like a better place for that.
