[llvm] [RISCV] Remove codegen for vp_fadd, vp_fmul (PR #191842)

Mon Apr 13 09:05:46 PDT 2026

https://github.com/lukel97 created https://github.com/llvm/llvm-project/pull/191842

Part of the work to remove trivial VP intrinsics from the RISC-V backend, see https://discourse.llvm.org/t/rfc-remove-codegen-support-for-trivial-vp-intrinsics-in-the-risc-v-backend/87999

This splits off 2 intrinsics from #179622. These are removed in lockstep as there are some combines that depend on these nodes like fadd + fmul -> fma.
