[LoongArch][CodeGen] Implement 128-bit and 256-bit vector shuffle. (#100054)
[LoongArch][CodeGen] Implement 128-bit and 256-bit vector shuffle
operations.
In LoongArch, shuffle operations can be divided into two types:
- Single-vector shuffle: Shuffle using only one vector, with the other
vector being `undef` or not selected by mask. This can be expanded to
instructions such as `vreplvei` and `vshuf4i`.
- Two-vector shuffle: Shuflle using two vectors. This can be expanded to
instructions like `vilv[l/h]`, `vpack[ev/od]`, `vpick[ev/od]` and the
basic `vshuf`.
In the future, more optimizations may be added, such as handling 1-bit
vectors and processing single element patterns, etc.
