Sjoerd Meijer	716abbb2f5	This converts a signed remainder instruction to unsigned remainder, which enables the code size optimisation to fold a rem and div into a single aeabi_uidivmod call. This was not happening before because sdiv was converted but srem not, and instructions with different signedness are not combined.
