[LLD] [MachO] Fix GCC build warnings
This fixes the following warnings produced by GCC 9:

../tools/lld/MachO/UnwindInfoSection.cpp: In function ‘bool canFoldEncoding(compact_unwind_encoding_t)’:
../tools/lld/MachO/UnwindInfoSection.cpp:404:44: warning: comparison between ‘enum<unnamed>’ and ‘enum<unnamed>’ [-Wenum-compare]
404 | static_assert(UNWIND_X86_64_MODE_MASK == UNWIND_X86_MODE_MASK, "");
