[PATCH v5 4/7] gdb/testsuite: fix gdb.base/msym-bp-shl when running with Clang

[Bruno Larsen]

When trying to test gdb.base/msym-bp-shl.exp using clang, it would have
many failures because one of the version of the foo function was being
optimized away. Adding __attribute__ ((used)) to it fixed this.
