d99f1cdd - [RISCV][llvm] Support INSERT_VECTOR_ELT codegen for P extension (#179471)

[RISCV][llvm] Support INSERT_VECTOR_ELT codegen for P extension (#179471) Add custom lowering for INSERT_VECTOR_ELT on P extension vector types using the MVM instruction. TODO: Handle <4 x i8> on RV64 which is constructed to extract_vector_elt + build_vector instead of insert_vector_elt.
