[PATCH][expmed.c] PR middle-end/77426 Delete duplicate condition in synth_mult

[Kyrill Tkachov]

Hi all,

The duplicate mode check in synth can just be deleted IMO. It was introduced as 
part of r139821 that was
a much larger change introducing size/speed differentiation to the RTL midend. 
So I think it's just a typo/copy-pasto.

Tested on aarch64-none-elf.
Ok?

Thanks,
Kyrill
