rikardfalkeborn 75caf8e4de Fix #8230: FP unknown evaluation order on comma expression in while clause (#1415) 
The while part of a do-while loop looks almost like a function call, so
extend the check for function calls to ignore while-statements.

Note that there was only an FP when checking c-code, since the check is
disabled for c++-code. Therefore, make sure the test cases are run on a
c-file.

IOBYTE 184537884f Don't remove the volatile keyword so we can properly overload functions. (#1218) 
* Don't remove the volatile keyword so we can properly overload functions.

I fixed all the checks that had tests that use volatile.  There will
probably be more changes needed due to lack of test coverage for
volatile in some checks.
