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

[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] 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.
