Wrap unsafe pointer arithmetic with WTF_ALLOW_UNSAFE_BUFFER_USAGE_BEGIN/END in two JSC files that trigger -Werror,-Wunsafe-buffer-usage with clang - InlineCacheHandler: m_jumpTarget computation offsets a CodePtr via dataLocation<uint8_t*>() + prologueSizeInBytesDataIC. - MarkedVector: expandCapacity() uses raw pointer indexing to copy buffer contents during reallocation.
