Obviously it would have been better for the first mov (or any op) to store
directly %esp[0] if there are no other uses.

We produce this:
LBB4_70: # cond_next603
movl -20(%ebp), %esi
movl L_tables$non_lazy_ptr-"L4$pb"(%esi), %esi
However, ICC caches this information before the loop and produces this:
movl 88(%esp), %eax #481.12
