[Bug middle-end/27663] missed-optimization transforming a byte array to unsigned long

[rguenth at gcc dot gnu dot org]

It's a target independent issue.  On non-strict alignment targets we can do a
32bit load instead of 4 byte loads.  This is what you ask for, correct?

combine unfortunately does not see enough insns to catch it.  Within a single
stmt we can teach fold to do it, otherwise forwprop is our tree level combiner.
