into the 10.x branch.  This fixes a new -Werror warning from clang 10.0.0 in
libunwind:

In file included from libunwind/src/libunwind.cpp:22:
libunwind/src/UnwindCursor.hpp:1455:51: error: operator '?:' has lower
precedence than '|'; '|' will be evaluated first
[-Werror,-Wbitwise-conditional-parentheses]
  _info.flags = isSingleWordEHT ? 1 : 0 | scope32 ? 0x2 : 0;  // Use enum?
                                      ~~~~~~~~~~~ ^
libunwind/src/UnwindCursor.hpp:1455:51: note: place parentheses around the '|'
expression to silence this warning
  _info.flags = isSingleWordEHT ? 1 : 0 | scope32 ? 0x2 : 0;  // Use enum?
                                                  ^
                                      (          )
libunwind/src/UnwindCursor.hpp:1455:51: note: place parentheses around the '?:'
expression to evaluate it first
  _info.flags = isSingleWordEHT ? 1 : 0 | scope32 ? 0x2 : 0;  // Use enum?
                                                  ^
                                          (                )
