Faster stack-protector for Android/AArch64. Bionic has a defined thread-local location for the stack protector cookie. Emit a direct load instead of going through __stack_chk_guard. llvm-svn: 265481

[Fuchsia] Use thread-pointer ABI slots for stack-protector and safe-stack The Fuchsia ABI defines slots from the thread pointer where the stack-guard value for stack-protector, and the unsafe stack pointer for safe-stack, are stored. This parallels the Android ABI support. Patch by Roland McGrath Differential Revision: https://reviews.llvm.org/D30237 llvm-svn: 296081
