Emit a context error and delete the instruction. This allows removing the AMDGPU hack where some atomic libcalls are falsely added. NVPTX also later copied the same hack, so remove it there too. For now just emit the generic error, which is not good. It's missing any useful context information (despite taking the instruction). It's also confusing in the failed atomicrmw case, since it's reporting failure at the intermediate failed cmpxchg instead of the original atomicrmw.
