For alignment purposes, the instruction array will always have an even number of entries, with the final entry potentially unused (in which case the array will be one longer than indicated by the count of unwind codes field). Reviewed by Anton Korobeynikov, Charles Davis and Nico Rieck. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190767 91177308-0d34-0410-b5e6-96231b3b80d8
