AVR: target/118878 - Don't ICE on result from paradoxical reg's alloc.
After register allocation, paradoxical subregs may become something
like r20:SI += r22:SI which doesn't make much sense as assembly code.
Hence avr_out_plus_1() used to ICE on such code. However, paradoxical
subregs appear to be a common optimization device (instead of proper
mode demotion).

paradoxical reg's register allocation.
