This patch adds a warning switch for "#pragma once in main file". The
warning option name is Wpragma-once-outside-header, which is the same
as Clang provides.

This fixes minor fallout from the IOR->ADD change for rotates that I
installed a little while ago.
Basically the SH backend has a special pattern for setting the T
register that has elements similar to a rotate. With the IOR->ADD
change that pattern no longer matches and we get scan-asm failu

The patch fails on arm because the tests make assumptions
about enums that are not true everywhere. Should we just
limit the tests to x86?

Oops this is wrong. I need to fix this and regtest again.

As an aside, simulavr tries to simulate an exact match of the hardware
including internal I/O like timers, IRQs, etc.
For GCC regression testing, no internal I/O
We still have newer ones and general links to the specifications.
