[PATCH] RISC-V: update prepare_ternary_operands to handle the vector-scalar case [PR120828]
This is a followup to 92e1893e0 "RISC-V: Add patterns for vector-scalar multiply-(subtract-)accumulate" that caused an ICE in some cases where the mult operands were wrongly swapped. This patch ensures that operands are not swapped in the vector-scalar case. PR target/120828 gcc/ChangeLog
