Test behaviour of watchpoints triggered by MOPS instructions. This test is similar to gdb.base/memops-watchpoint.exp, but specifically for MOPS instructions rather than whatever instructions are used in the libc's implementation of memset/memcpy/memmove. There's a separate watched variable for each set of instructions so that the testcase can test whether GDB correctly identified the watchpoint that triggered in each case.
