Description
The changes for 6873116 moved the reexecute bit into the PcDesc but didn't account for the code in DebugInformationRecorder that tries to share them. Since the code isn't checking should_reexecute it can merge PcDescs with different reexecute bits. The fix is to check that when merging them. The original code in 6833129 doesn't have this problem because the bit was in the stream.
