Some of the borrowck field-sensitivity test functions have 'use' in their name, but they don't refer to the specific kind of use (whether a copy or a deref). It would be better if the name more precisely reflected what the function is testing.
A number of borrowck field-sensitivity tests perform more moves and copies than their naming scheme would indicate. This is only necessary for borrowed pointers (to ensure that the borrowws stay alive in the near future when borrow liveness is tracked), but all other test functions should be changed to match their name more closely.
Add more borrowck field-sensitivity tests for functional update moves. This makes the collection of test functions more combinatorially exhaustive.
The move_after_borrow / fu_move_after_borrow tests in run-pass/borrowck-field-sensitivity.rs are not testing the right thing, since the scope of the borrow is limited to the call to borrow(). When fixed, these tests fail and thus should be moved to the corresponding compile-fail test file.
Instead of calling a borrow() function that takes a pointer type, just create a local pointer and dereference it. The dereference is there to outsmart any future liveness analysis in borrowck.

After sitting down to build on the work merged in #14318, I realized that some of the test names were not clear, others probably weren't testing the right thing, and they were also not as exhaustive as they could have been.
