Ryan Prichard 729899f7b6 [libunwind] unw_* alias fixes for ELF and Mach-O ... Rename the CMake option, LIBUNWIND_HERMETIC_STATIC_LIBRARY, to LIBUNWIND_HIDE_SYMBOLS. Rename the C macro define, _LIBUNWIND_DISABLE_VISIBILITY_ANNOTATIONS, to _LIBUNWIND_HIDE_SYMBOLS, because now the macro adds a .hidden directive rather than merely suppress visibility annotations. For ELF, when LIBUNWIND_HIDE_SYMBOLS is enabled, mark unw_getcontext as hidden. This symbol is the only one defined using src/assembly.h's WEAK_ALIAS macro. Other unw_* weak aliases are defined in C++ and are already hidden. Mach-O doesn't support weak aliases, so remove .weak_reference and weak_import. When LIBUNWIND_HIDE_SYMBOLS is enabled, output .private_extern for the unw_* aliases. In assembly.h, add missing SYMBOL_NAME macro invocations, which are used to prefix symbol names with '_' on some targets. Fixes PR46709.
