This PR changes how LLVM is built. Consider updating src/bootstrap/download-ci-llvm-stamp. |

hm, probably current implementation won't work. IIUC target LLVM is used when rustc is being profiled... |

yeah, that doesn't work |

when compiling target LLVM with `opt-dist local` on Windows/MinGW, profraw files are being compressed with zlib, so compiling without it will make `llvm-profdata` complain about lacking of zlib support. this error is shown: `profile uses zlib compression but the profile reader was built without zlib support` example from llvm test suite: https://github.com/llvm/llvm-project/blob/76b5fcbf975547251faaeed8b567ea09d139a607/llvm/test/tools/llvm-profdata/nocompress.test#L15

This likely won't work because you need zlib library and headers on CI. |

I'm sure that they are installed somewhere else. or they aren't? |

looked at CI build. CMake couldn't find Zlib, but build doesn't fail, so probably nothing changed for resulting LLVM |
