[docs] Fixed the flag used to debug with gdb and lli using jit in docs.

Summary

In the "Debugging MCJIT-ed code" doc, -use-mcjit is described as the flag to be used. I think it should be -jit-kind=mcjit instead.

Looks good to me. Thanks Jian!

Do you have commit access? If not I can commit this on your behalf.

 Debugging MCJIT-ed code
 =======================
 
 The emerging MCJIT component of LLVM allows full debugging of JIT-ed code with
 GDB.  This is due to MCJIT's ability to use the MC emitter to provide full
 DWARF debugging information to GDB.
 
-Note that lli has to be passed the ``-use-mcjit`` flag to JIT the code with
+Note that lli has to be passed the ``-jit-kind=mcjit`` flag to JIT the code with
 MCJIT instead of the old JIT.
 
 Example
 -------
 
 Consider the following C code (with line numbers added to make the example
 easier to follow):
 
.. code-block:: c
    22  }
 
 Here is a sample command line session that shows how to build and run this
 code via ``lli`` inside GDB:
 
 .. code-block:: bash
 
    $ $BINPATH/clang -cc1 -O0 -g -emit-llvm showdebug.c
-   $ gdb --quiet --args $BINPATH/lli -use-mcjit showdebug.ll 5
+   $ gdb --quiet --args $BINPATH/lli -jit-kind=mcjit showdebug.ll 5
    Reading symbols from $BINPATH/lli...done.
    (gdb) b showdebug.c:6
    No source file named showdebug.c.
    Make breakpoint pending on future shared library load? (y or [n]) y
    Breakpoint 1 (showdebug.c:6) pending.
    (gdb) r
-   Starting program: $BINPATH/lli -use-mcjit showdebug.ll 5
+   Starting program: $BINPATH/lli -jit-kind=mcjit showdebug.ll 5
    [Thread debugging using libthread_db enabled]
 
    Breakpoint 1, compute_factorial (n=5) at showdebug.c:6
    6      int f = n;
    (gdb) p n
    $1 = 5
    (gdb) p f
    $2 = 0
