…, r=varkor Enable opting out of specific default LLVM arguments. `rustc` by default adds a few arguments to LLVM (like `-mergefunc-use-aliases` for example). With this PR `rustc` will only emit these arguments if the same argument has not already been specified by the user via `-Cllvm-args`. This enables opting out of these defaults. The PR also removes a PGO specific `-Z` flag the effect of which can also be easily achieved by `-Cllvm-args`. Fixes rust-lang#64310.

The same effect can be achieved by `-Cllvm-args=-disable-preinline`.
