Fix test after renaming -name-anon-functions pass to -name-anon-globals llvm-svn: 281752

[ThinLTO] Ensure anonymous globals renamed even at -O0 Summary: This fixes an issue when files are compiled with -flto=thin at default -O0. We need to rename anonymous globals before attempting to write the module summary because all values need names for the summary. This was happening at -O1 and above, but not before the early exit when constructing the pipeline for -O0. Also add an internal -prepare-for-thinlto option to enable this to be tested via opt. Fixes PR30419. Reviewers: mehdi_amini Subscribers: probinson, llvm-commits, mehdi_amini Differential Revision: https://reviews.llvm.org/D24701 llvm-svn: 281840

Add a pass to name anonymous/nameless function Summary: For correct handling of alias to nameless function, we need to be able to refer them through a GUID in the summary. Here we name them using a hash of the non-private global names in the module.

Fix NameAnonFunctions pass: for ThinLTO we need to rename global variables as well A follow-up patch will rename this pass and the source file accordingly, but I figured the non-NFC change will be easier to spot in isolation. Differential Revision: https://reviews.llvm.org/D24641 llvm-svn: 281744
