  -----------
  [CIR][AMDGPU] Add support for AMDGCN rcp builtins (#197447)

Adds codegen for the following AMDGCN reciprocal builtins:

- __builtin_amdgcn_rcp (double)
- __builtin_amdgcn_rcpf (float)
- __builtin_amdgcn_rcph (half)
- __builtin_amdgcn_rcp_bf16 (bfloat16)

These are lowered to the corresponding `llvm.amdgcn.rcp` intrinsic.
