    PR10274 Fix exelib -O3 testcase.
    
    The testcase now uses noinline, an empty asm statement and a volatile
    variable to prevent the function getting inlined, being totally unrolled
    or the recursive call being replaced with an inner-iteration.
    
    This does defeat part of the testcase though, which was testing unwinding
    through an optimized recursive function. But it seems the best we can do.
    
    * testsuite/systemtap.exelib/exelib.exp: Add -O3 to the mix.
    * testsuite/systemtap.exelib/uprobes_exe.c: Use volatile bar and mark
      main_func noinline.
    * testsuite/systemtap.exelib/uprobes_lib.c: Use volatile foo and mark
      lib_func noinline.
