Another issue with erroneous array types. When an erroneous array
type is in a function's signature, particularly the return type, we
must guarantee that type is changed into an error type. Otherwise,
any operations that work on arrays and slices will crash when applied
to the erroneous array return type.
Fixesgolang/go#12939.

The gofrontend asks the backend compiler for the architecture
appropriate size of a given type. For array types, it is possible
to construct a type too large to fit on the machine. This patch does
two things: 1. When an impossibly large type is encountered, we mark
the type as erroneous and later calls to discover the size of that
type are short-circuited. 2. When generating the GC symbol data for
an impossibly large array of arrays, we avoid generating symbol data
as soon as we find an array that is too large to be expressed.
Fixesgolang/go#12938.

As described in the PR, wi::divmod_internal was sign- rather than
zero-extending a modulus result in cases where the result has fewer
HWIs than the precision and the upper bit of the upper HWI was set.

to handle the canonicalisation step itself.
Tested on x86_64-linux-gnu. I added tests to the wide-int
plugin since that seemed more direct.
