V2:
- Remove unnecessary syntax changes in generic-ooo
- Add new vector crypto reservations and types to
  pipelines
V3:
- Move all vector pipelines into separate file which defines all ooo vector
  reservations.
- Add temporary attribute while cost model changes.
V4:
- No change

Hi Edwin,

Looks like 6ec84c45a19403d3435b2affe4ec60e518fc1f97 result in sorts of rvv.exp asm check failure (I list some but not all of them in below) in upstream.
Could you please help to double check about it? Ping me if any more information is needed. Thanks.
