    Fix fail in mi-var-child.exp and mi-var-display.exp
    
    Hi,
    I see the following fails on arm-none-eabi target,
    
    -var-list-children --simple-values struct_declarations  ^M
    ^done,numchild="11",children=[...,child={name="struct_declarations.func_ptr_struct",exp="func_ptr_struct",numchild="0",value="0x0 <_ftext>",type="struct _struct_decl (*)(int, char *, long)",thread-id="1"},child={name="struct_declarations.func_ptr_ptr",exp="func_ptr_ptr",numchild="0",value="0x0 <_ftext>",type="struct _struct_decl *(*)(int, char *, long)",thread-id="1"},...
    (gdb) ^M
    FAIL: gdb.mi/mi-var-child.exp: listing of children, simple types: names, type and values, complex types: names and types
    
    -var-set-format weird.func_ptr_ptr natural^M
    ^done,format="natural",value="0x0 <_ftext>"^M
    (gdb) ^M
    FAIL: gdb.mi/mi-var-display.exp: set format variable weird.func_ptr_ptr in natural
    
    In the test, "0x0" is expected, but "0x0 <_ftext>" is in the output.
    Function pointers point to address zero, and tests assume there is no
    symbol on address zero.  However, on my arm-none-eabi target, there is
    a code symbol _ftext on address zero, and test fails.  Note that "set
    print symbol off" doesn't take effect for function pointer.
    
    int (*f) (void);
    f = main;
    
    (gdb) p f
    $1 = (int (*)(void)) 0x8048400 <main>
    (gdb) set print symbol off
    (gdb) p f
    $2 = (int (*)(void)) 0x8048400 <main>
    
    In order to erase the difference, we can assign some function address
    explicitly to function pointer, so the test behaves in a unique way.
    In this patch, we assign nothing1 and nothing2 to function pointers
    func_ptr_struct and func_ptr_ptr respectively, and update test as the
    source file is changed.

    Use mi_varobj_update in mi-var-child.exp and mi2-var-child.exp
    
    Hi,
    I modify mi-var-child.exp and find that the pattern to match the output
    of -var-update * is quite complicated.  However, it can be simplified by
    using mi_varobj_update.  That is what this patch does.
    
    gdb/testsuite:
    
    2014-10-14  Yao Qi  <yao@codesourcery.com>
    
    	* gdb.mi/mi-var-child.exp: Use mi_varobj_update to simplify
    	tests.
    	* gdb.mi/mi2-var-child.exp: Likewise.
