Summary:
I've added a test case that (without the fix) triggers the assertion,
which happens when a move happens in an implicitly called conversion
operator.
This patch also fixes nondeterministic behavior in the source code
location reported for the move when the move is constained in an init list;
this was causing buildbot failures in the previous attempt to submit
this patch (see D30569 and rL297004).

Summary:
As a unique_ptr or shared_ptr that has been moved from is guaranteed to be null,
we only warn if the pointer is dereferenced.

Summary:
This adds a diagnostic to the misc-use-after-move check that is output when the
use happens on a later loop iteration than the move, for example:
A a;
for (int i = 0; i < 10; ++i) {
a.foo();
std::move(a);
}
This situation can be confusing to users because, in terms of source code
location, the use is above the move. This can make it look as if the warning
is a false positive, particularly if the loop is long but the use and move are
close together.
In cases like these, misc-use-after-move will now output an additional
diagnostic:
a.cpp:393:7: note: the use happens in a later loop iteration than the move

Summary:
The check warns if an object is used after it has been moved, without an
intervening reinitialization.
See user-facing documentation for details.
