8016697: Use stubs to implement safefetch

Implement Safefetch as stub routines. This reduces compiler and os dependencies.

JDK-8016697.patch

pengying-flora commented 3 months ago

在os_linux_aarch64.cpp和os_linux_riscv.cpp文件里定义的函数address os::Posix::ucontext_get_pc(const ucontext_t * uc) aarch64是uc_mcontext.pc，为何riscv就是uc_mcontext.__gregs[REG_PC] uc_mcontext貌似是/usr/include/sys/ucontext.h里定义的结构体
