History
Konstantin Belousov 1947b29861 amd64: Streamline exceptions and interrupts handlers. 
PTI-mode entry points were coded to set up the environment identical
to non-PTI entry and then fall-through to non-PTI handlers, mostly.
This has the drawback of requiring two more SWAPGS, first to access
PCPU, and then to return to the state expected by the non-PTI entry
point.

Eliminate the duplication by doing more in entry stubs both for PTI
and non-PTI, and adjusting the common code to expect that SWAPGS and
some minimal registers saving is done by entries.

Some less often used entries, in particular, #GP, #NP, and #SS, which
can fault on doreti, are left as is because there are basically four
variants of entrance, and they are not performance-critical,
esp. comparing with e.g. #PF or interrupts.
