Fix some misleading target feature aliases This is the first half of a fix for #100752. It looks like these aliases were added in #78361 and slipped under the radar, as these features are not AVX512. These features _do_ add AVX512 instructions when used _in combination_ with AVX512F, but without AVX512F, these features still provide 128-bit and 256-bit vector instructions. A user might be mislead into thinking these features imply AVX512F (which is true of the actual AVX512 features). This PR allows using the names as defined by LLVM, which matches Intel documentation. A future PR should change the `std::arch` intrinsics to use these names, and finally remove these aliases from rustc. r? ```@workingjubilee``` cc ```@Amanieu``` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
