Jiaxun Yang fdd12a80f6 ptrace: Introduce exception_ip arch hook 
[ Upstream commit 11ba1728be ]

On architectures with delay slot, architecture level instruction
pointer (or program counter) in pt_regs may differ from where
exception was triggered.

Introduce exception_ip hook to invoke architecture code and determine
actual instruction pointer to the exception.
