Teresa Johnson 68406a2c5d [ThinLTO] Make inline assembly handling more efficient in summary ... Summary: The change in r285513 to prevent exporting of locals used in inline asm added all locals in the llvm.used set to the reference set of functions containing inline asm. Since these locals were marked NoRename, this automatically prevented importing of the function. Unfortunately, this caused an explosion in the summary reference lists in some cases. In my particular example, it happened for a large protocol buffer generated C++ file, where many of the generated functions contained an inline asm call. It was exacerbated when doing a ThinLTO PGO instrumentation build, where the PGO instrumentation included thousands of private __profd_* values that were added to llvm.used. We really only need to include a single llvm.used local (NoRename) value in the reference list of a function containing inline asm to block it being imported. However, it seems cleaner to add a flag to the summary that explicitly describes this situation, which is what this patch does.
