I started to suggest using :inoremap to define your mapping since
that will ignore any mappings of keys used on the rhs of the
mapping. However, as I was verifying the problem I discovered that
the problem doesn't exist for me. Starting Vim like this,

"C:\Program Files\vim\vim73\gvim.exe" -u NONE -i NONE

and executing either

:set ai

or

:filetype indent on
:set ft=cpp

before pasting your original code using <S-Insert> resulted in
the same indentation as the original code. This was using Vim
7.3.600 on Windows XP.

I think something in your configuration is causing the problem.

:help <S-Insert>

says that that keycode is already mapped to

<C-R><C-O>*

(which I verified) and

:help i_CTRL-R_CTRL-O

says that that command inserts the contents of a register literally
and without auto-indenting.

So, you shouldn't be seeing any auto-indenting when you paste with
<S-Insert>. What do you see when you execute

:imap <S-Insert>

?
