The code density registers are NOT saved on the stack.
This is controlled by bit 13 in AUX_IRQ_CTRL, which didn't even have a symbol
defined for it. I've also added _ARC_V2_AUX_IRQ_CTRL_LP for bit 13.

The .nd on a branch is WRONG if its an unconditional branch. Not needed.
On conditional branches its a compiler feature that is not yet functional
with ARC targets. Typical code for this compiler can use .d to put
something in the delay slot of an instruction, but using .nd is probably
never wanted.

By using isa-16 instructions, a bit of code-size can be saved,
and code can be a little faster.

The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.
APIs that had their names changed:
- nano_context_id_t is now nano_thread_id_t
- context_self_get() is now sys_thread_self_get()
- context_type_get() is now sys_execution_context_type_get()
- context_custom_data_set/get() are now
sys_thread_custom_data_set/get()
The 'context' prefix namespace does not have to be reserved by the
kernel anymore.
The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):
- struct ccs is now struct tcs
- tCCS is now tTCS

The change replaces multiple asterisks to ** at
the beginning of comments and adds a space before
the asterisks at the beginning of lines.

The new name better reflects that this file contains all private
nanokernel APIs that are used by various kernel subsystems.
