The atomicalign checker detects non-64-bit aligned struct field
arguments to sync/atomic functions but currently misses out cases
where the struct variable identifier is a pointer to struct. This
is very common as it happens when the 64-bit field is accessed
in a method with pointer receiver, where the struct is itself the
method receiver. Add some tests to cover that new case.
While I'm at it, fix some typos.
