Aarch64 sim fix for gcc-10 miscompilation.
This fixes a problem that occurs when compiled by gcc-10, as the code
is relying on undefined overflow behavior. This is fixed by replacing
compares between 32-bit and 64-bit results with compares that just use
the 64-bit results with a cast.
PR sim/27483
* simulator.c (set_flags_for_add32): Compare uresult against
itself. Compare sresult against itself.
