Objective-C Class Properties: Autoupgrade "Class Properties" module flag. When we have "Image Info Version" module flag but don't have "Class Properties" module flag, set "Class Properties" module flag to 0, so we can correctly emit errors when one module has the flag set and another module does not. rdar://26469641 llvm-svn: 270791

[AMDGPU] Rename COV module flag to amdhsa_code_object_version (#79905) The previous name 'amdgpu_code_object_version', was misleading since this is really a property of the HSA OS. The new spelling also matches the asm directive I added in bc82cfb.

[IR] AutoUpgrade ModuleFlagBehavior for PIC and PIE level Summary: From r303590, ModuleFlagBehavior for PIC and PIE level is changed from Error to Max. This will cause bitcode compatibility issue when linking against a bitcode static archive built with old compiler. Add an auto-ugprade path to upgrade the the ModuleFlagBehavior in the old bitcode to match the new one so IRLinker can link them.

[AutoUpgrade] Fix a compatibility issue with module flag Summary: After r304661, module flag to record objective-c image info section is encoded without whitespaces after comma. The new name is equivalent to the old one, except that when LTO a module built by old compiler and a module built by a new compiler, it will fail with conflicting values. Fix the issue by removing whitespaces in bitcode upgrade path. rdar://problem/34416934 Reviewers: compnerd Reviewed By: compnerd Subscribers: mehdi_amini, hans, llvm-commits Differential Revision: https://reviews.llvm.org/D37909 llvm-svn: 313398

[IR] Use Min behavior for module flag "PIC Level" Using Max for both "PIC Level" and "PIE Level" is inconsistent. PIC imposes less restriction while PIE imposes more restriction. The result generally picks the more restrictive behavior: Min for PIC. This choice matches `ld -r`: a non-pic object and a pic object merge into a result which should be treated as non-pic. To allow linking "PIC Level" using Error/Max from old bitcode files, upgrade Error/Max to Min. Reviewed By: tejohnson Differential Revision: https://reviews.llvm.org/D130531
