Rollup merge of #92516 - Kobzol:bootstrap-symbol-mangling, r=Mark-Simulacrum
Do not use deprecated -Zsymbol-mangling-version in bootstrap `-Zsymbol-mangling-version` now produces warnings unconditionally. So if you want to use legacy mangling for the compiler (`new-symbol-mangling = false` in `config.toml`), the build is now littered with warnings. However, with this change, stage 1 `std` doesn't compile: ``` error: `-C symbol-mangling-version=legacy` requires `-Z unstable-options` ``` Even after the bootstrap compiler is updated and it will support `-Csymbol-mangling-version`, the bootstrap code would either need to use `-Z` for the legacy mangling or use `-C` in combination with `-Z unstable-options` (because `-C` + legacy is not allowed without the unstable options). Should we just add `-Z unstable-options` to `std` compilation to resolve this? Btw I use legacy mangling because the new mangling is not supported by [Hotspot](https://github.com/KDAB/hotspot).
