In the process of running this check on a large codebase I found a
number of limitations, and thought I would pass on my fixes for
possible integration upstream:
* Templated function call operators are not supported
* Function object constructors are always used directly in the lambda
body, even if their arguments are not captured
* Placeholders with namespace qualifiers (std::placeholders::_1) are
not detected
* Lambda arguments should be forwarded to the stored function
* Data members from other classes still get captured with this
* Expressions (as opposed to variables) inside std::ref are not captured
properly
* Function object templates sometimes have their template arguments
replaced with concrete types
This patch resolves all those issues and adds suitable unit tests.
This represents largely a full re-write of modernize-avoid-bind, adding
significant new functionality in the process. In particular:
* Both boost::bind and std::bind are now supported
* Function objects are supported in addition to functions
* Member functions are supported
* Nested calls are supported using capture-init syntax
* std::ref() and boost::ref() are now recognized, and will capture by reference.
* Rather than capturing with a global =, we now build up an individual
capture list that is both necessary and sufficient for the call.
* Fixits are supported in a much larger variety of scenarios than before.
All previous tests pass under the re-write, but a large number of new
tests have been added as well.

Summary:
This change moves tests for checkers and infrastructure into separate
directories, making it easier to find infrastructure tests. Tests for
checkers are already easy to find because they are named after the
checker. Tests for infrastructure were difficult to find because they
were outnumbered by tests for checkers. Now they are in a separate
directory.
