Thanks @junrushao1994 @comaniac |

The ROCm default detection seems to have been mangled to confuse ROCm version (software) with compute arch (hardware, e.g. gfx). I'll try to fix it. |

@t-vi Yes, the detection logic used previously in amdgpu codegen is here: https://github.com/apache/incubator-tvm/blob/e5b793f39fd5b4f84b0aedf06aa376ebe45cf2bc/src/target/llvm/codegen_amdgpu.cc#L194. Then I moved the logic to the target constructor to reveal it at earliest stage. |

@t-vi I see. We should change this line: https://github.com/apache/incubator-tvm/blob/master/src/target/target_kind.cc#L176, from |

I'll just send a PR in a minute or so. |

This PR uses target class to replace almost all the raw target strings in all the codegen modules. It further helps with us migration towards a robost JSON-like targets configuration, per [RFC] TVM Target Specification.
The only place that uses raw string is what is stored in tvm_target in LLVM module's metadata. In this case, we know that we only care about "mtriple", "mattr", "mcpu", "mfloat-abi", so we only store those attributes in the metadata.
