Rollup merge of #67393 - michaelwoerister:llvm-args-override, 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 https://github.com/rust-lang/rust/issues/64310.
