My bootstrap/regtest (of essentially the first patch above) went fine, but I
agree that the addition of side_effects_p guard in reload_cse_simplify_operands
is probably the right thing to do too.  I like the first patch over the second
since we are able to replace the redundant load with a simple increment.

I'll bootstrap/regtest the additional change.
