[Bug c++/41997] [C++0x] constant initializer_list not optimised

Sorry, one important thing I missed off my bug report. This problem seems to
just be connected to constant lists. The following is fully optimised away

int i = 1, j = 2;
return max_val({i,j});

As is the following, despite the fact the code never access the third element
of the initializer_list

int i = 1;
return max_val({1,2,i});

So this really seem to be some (mis)optimisation involving constant lists.
