[PATCH v2] arm: Prevent ICE when doloop dec_set is not PLUS_EXPR

Resending as v2 so CI picks it up. This patch refactors and fixes an issue where arm_mve_dlstp_check_dec_counter was making an assumption about the form of what a candidate for a dec_insn. This dec_insn is the instruction that decreases the loop counter inside a decrementing loop and we expect it

arm: Prevent ICE when doloop dec_set is not PLUS_EXPR

This patch refactors and fixes an issue where arm_mve_dlstp_check_dec_counter was making an assumption about the form of what a candidate for a dec_insn. It also makes sure that if it does not initially encounter a 'set' in such a form it tries to find another set that could be the right one.
