These functions are frequently optimized with specialized instructions that favor larger memory access operations, so make sure GDB behaves correctly in their presence. There's a separate watched variable for each function so that the testcase can test whether GDB correctly identified the watchpoint that triggered. Also, the watchpoint is 28 bytes away from the beginning of the buffer being modified, so that large memory accesses (if present) are exercised.
