bugprone-argument-comment

Checks that argument comments match parameter names.

The check understands argument comments in the form /*parameter_name=*/ that are placed right before the argument.

void f(bool foo);

...

f(/*bar=*/true);
// warning: argument name 'bar' in comment does not match parameter name 'foo'

The check tries to detect typos and suggest automated fixes for them.
