    Ensure that array types with complicated length expressions are
    handled correctly by lowering expression types in the lowering pass.
    
    This required some adjustment of constant expression types to not
    report too many errors for circular constant expressions.  We now
    record error types in the Named_constant type.  If we find the
    circularity due to lowering the Named_constant, we use that location
    for the error message; this retains the error location we used to use.

Using pointer sized variables (e.g. size_t / ptrdiff_t) when the
variables are used as array indices allows accessing larger arrays,
and can be a slight performance improvement due to no need for sign or
zero extending, or masking.

As part of the change to larger character lengths, the string copy
algorithm was temporarily pessimized to get around some spurious
-Wstringop-overflow warnings.  Having tried a number of variations of
this algorithm I have managed to get it down to one spurious warning,
only with -O1 optimization, in the testsuite.  This patch reinstates
the optimized variant and modifies this one testcase to ignore the
warning.
