Jim Cromie 15d4734c7a checkpatch: qualify do-while-0 advice ...

Add a paragraph of advice qualifying the general do-while-0 advice, noting
3 possible misguidings.  reduce one ERROR to WARN, for the case I actually
encountered.

And add 'static_assert' to named exceptions, along with some additional
comments about named exceptions vs (detection of) declarative construction
primitives (union, struct, [], etc).
