    gdb/testsuite: Add gdb.base/memops-watchpoint.exp

    Test behaviour of watchpoints triggered by libc's memset/memcpy/memmove.
    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.
