It is otherwise impossible to determine which test failed sanitizer/valgrind
check. test/functional/helpers.lua module return was changed so that tests which
do not provide after_each function to get new check will automatically fail.

"Add missing test files from 7.4.634 to the repository."
The discrepancy between the expected getpos() result of the old test
[0, 15, 2, 0] and the converted test [0, 3, 2, 0] is just a matter of how
the buffer is constructed: in the old Vim test the buffer has a bunch of
junk at the top.
The central purpose of the test is to verify that the getpost("'a") does
*not* return [0, 0, 0, 0].
