fix skipping of cpp attributes. (#4971) 
* fix skipping of cpp attributes.

* fix simplifyCPPAttribute loop.

When the first token was the start of a c++ attribute on a function,
so that tok->previous() was nullptr at the bottom of the loop,
an extra token would be skipped.  This could result in the corresponding
function being omitted from the symbol table.

* fix alignas test failure, enhance cpp attr test.

* uncrustify.

* fix redundantNextPrevious

* delete redundant code.

* add some tokenizer tests for simplifyCPPAttribute.

* enhance noreturn symbol test.

The order of a noreturn attribute and another attribute used to
matter.  Test both orders.
