570f3622 - AMDGPU: Fix legalization for llvm.amdgcn.raw.buffer.atomic.fadd.v2bf16

AMDGPU: Fix legalization for llvm.amdgcn.raw.buffer.atomic.fadd.v2bf16 We somehow ended up with llvm.amdgcn.raw.ptr.buffer.atomic.fadd, and llvm.amdgcn.raw.buffer.ptr.atomic.fadd.v2bf16 intrinsic definitions, despite the second being the canonical mangling for the first intrinsic with v2bf16. This requires us to handle it as a separate case. Surprisingly, cases generating the regular 1st intrinsic with bfloat end up getting ID'd as the second. The selection is still broken for the gfx9 cases.
