Ard Biesheuvel a19da876ab [ARM] implement support for TLS register based stack protector ...

Implement support for loading the stack canary from a memory location held in
the TLS register, with an optional offset applied. This is used by the Linux
kernel to implement per-task stack canaries, which is impossible on SMP systems
when using a global variable for the stack canary.
