The .personalityindex directive is equivalent to the .personality directive with the ARM EABI personality with the specific index (0, 1, 2). Both of these directives indicate personality routines, so enhance the personality directive handling to take into account personalityindex. Bonus fix: flush the UnwindContext at the beginning of a new function. Thanks to Logan Chien for additional tests! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199706 91177308-0d34-0410-b5e6-96231b3b80d8
