testcase

This is extracted (and simplified a bit) from 8886 so that we have one case per
bug.

With gcc 4.8 the main function compiles down to just

main:
        pushq   %rbx
        movl    $3, %ebx
.L11:
        xorl    %eax, %eax
        movl    $3, %esi
        movl    $.LC0, %edi
        call    printf
        subl    $1, %ebx
        jne     .L11
        xorl    %eax, %eax
        popq    %rbx
        ret
