[llvm] [AMDGPU] Remove unused TableGen generated enum (PR #171170)

[Mirko Brkušanin via llvm-commits]

https://github.com/mbrkusanin created https://github.com/llvm/llvm-project/pull/171170

This GenericEnum was just adding separate values for VOP3P_Pseudo opcodes
in the same namespace as existing opcodes that did not match. They were
defined in AMDGPUGenSearchableTables.inc by tablegen emitter but were
guarded out by #ifdef. Because of that, they were never included in the
code, so the compiler never reported the naming conflict and the bug never
had a chance to surface.
