Duncan Sands 77a1f3b564 Don't perform an overaligned load in this test, since that's undefined 
behaviour that might be exploited one day.

Duncan Sands 0b875a0c29 When folding a load from a global constant, if the load started in the middle 
of an array element (rather than at the beginning of the element) and extended
into the next element, then the load from the second element was being handled
wrong due to incorrect updating of the notion of which byte to load next.  This
fixes PR13442.  Thanks to Chris Smowton for reporting the problem, analyzing it
and providing a fix.
