Fix spurious FAILs with examine-backward.exp
The test case examine-backward.exp issues the command "x/-s" after the end of the first string in TestStrings, but without making sure that this string is preceded by a string terminator. Thus GDB may spuriously print some random characters from before that string, and then the test fails. This patch assures that TestStrings is preceded by a string terminator. gdb/testsuite/ChangeLog: * gdb.base/examine-backward.c (Barrier): New character array constant, to ensure that TestStrings is preceded by a string terminator.
