Helper function to prepare parameters for Thread::kickoff.
This function will copy the first parameter for the kickoff function from the non-scratch register r15 into the register rdi (which is the first parameter according to the SystemV ABI).
context_switch jumps to this function on the first execution of a new context. The value mentioned above was placed on the stack by prepareContext during initialization and loaded into the register r15 while restoring the context in context_switch.

Panic function.
If the kickoff function (assigned in prepareContext) returns, this parameterless function will be called – and stop the execution.
