This patch reworks the current ARM __swap() function into a C function.
Due to some issues with using svc calls withing fault handlers, we
needed to change the way we initiate a swap by removing the dependence
on svc #0.
Before __swap() is called, the system has already done an irq_lock().
Upon return from __swap(), the equivalent of an irq_lock() is done due
to restoration of the key value from the irq_lock preceeding the call.
For ARM V6M (M0/M0+), the pendsv bit is toggled and the irqs are
enabled. There is no priority masking in v6m, so it's just a global
enable. For ARM V7M, the priority mask has to be set to 0x0 to allow
for the pendsv IRQ to be taken. This is done for both via a call to
irq_unlock(0).
After this unlock, a pendsv irq will be taken, either at the tail end
of the current irq handling if we are in handler mode, or immediately
due to the pendsv being asserted (no other outstanding irqs). The next
thread will be scheduled.
Upon return from the context switch to the original
thread, the priority mask will already be correct due to the pendsv
processing.

The root cause for this issue was found in
https://github.com/zephyrproject-rtos/zephyr/issues/6470
so this kconfig isn't needed anymore.
This is a partial reversion of 6eef2f14. The actual feature is left
in place, as it's plausibly useful in other contexts (otherwise
assertions enabled by sanitycheck can't be disabled by the app as
they're passed in via CFLAGS).

This was a little embarassing. The swap code got this right, and the
interrupt exit path got it right, but on entry we weren't ever saving
the shift and loop registers for the interrupted context.
This almost always worked anyway as the loop registers aren't ever
used in any Zephyr code (gcc won't generate this style of loop AFAICT)
and the SAR shift amount register is generally used only in two pairs
of adjacent instructions making the chance of hitting that exact cycle
quite low in general.
But of course we have shift-happy crypto code in our tests, so this
got caught, thankfully.
