cmd/compile: adjust some AMD64 rewrite rules to use typed aux fields

Remove an extra int32-representable check when deciding to use an int32
constant as an immediate value.

Comment out a broken optimization that relies on MaxUint32 being
representable by a signed int32. It never triggers and when fixed, the
signedness of the auxint prevents other optimization passes from
handling it properly, thus causing segfaults in the runtime.

Remove a couple offset representable in 32-bits checks on 32-bit aux
vals.
