[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.
