When adding the initializer for an array, we need to make sure that
array bounds are properly simplified if that array is a PARAMETER.
Otherwise the generated initializer could be wrong and screw up
subsequent simplifications, see PR.
The minimal solution is to attempt simplification of array bounds
before adding the initializer as in the attached patch. (We could
place that part in a helper function if this functionality is
considered useful elsewhere).
Regtested on x86_64-pc-linux-gnu. OK for mainline?
OK. Thanks for the patch,
