[Bug middle-end/40060] [4.5 Regression] casts loose alignment info

[pinskia at gcc dot gnu dot org]

Actually a cast to a lower alignment is valid (to an bigger alignment is
questionable if the pointer is not already aligned).
And this is a regression from the 4.4 as these testcases passed.  Really expand
should look through NOPs.
