2a8a694b - [RISCV][llvm] Handle calling convention for P extension fixed vectors (#176093)

[RISCV][llvm] Handle calling convention for P extension fixed vectors (#176093) P extension packed SIMD types are passed in GPRs. For types larger than XLen (e.g. v8i8 on RV32), they are split and passed via the 2XLen mechanism, similar to i64 on RV32. FIXME: Need to figure out the mechanism when P and V are enabled at the same time. stack on: https://github.com/llvm/llvm-project/pull/176193
