We can go with 2 or 3 (if needed) for now but should later
really incorporate reg-move costs in this IMHO. Just like e.g.
static const
1. This patch set scalar_to_vec cost as 2 instead 1 since scalar move
instruction is slightly more costly than normal rvv instructions (e.g.
vadd.vv).
2. Adjust scalar_to_vec cost accurately according to the splat value, for
example,
a value like 32872, needs 2 more scalar instructions:
