Also directly use an array instead of going through a tuple. This
reduces the amount of llvm ir lines for this function by almost half
from 3086 to 1662.
Remove `NullOp::Box`
Follow up of #89030 and MCP rust-lang/compiler-team#460.
~1 month later nothing seems to be broken, apart from a small regression that #89332 (1aac85bb716c09304b313d69d30d74fe7e8e1a8e) shows could be regained by remvoing the diverging path, so it shall be safe to continue and remove `NullOp::Box` completely.

This allows executing it like cargo clif build if you add it to your
PATH. It also fixes infinite recursion on Windows when invoking it as
Windows includes the current directory in PATH by default.
Fixes#971
Remove `SymbolStr`
This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences.

This reverts commit a1037fad7d.
There are two regressions in Cranelift with respect to small integer
operations. Both have already been fixed on thebmain branch, but we will
have to wait for a new Cranelift release. They have been fixed by
bytecodealliance/wasmtime#3610 and bytecodealliance/wasmtime#3617.
By changing `as_str()` to take `&self` instead of `self`, we can just
return `&str`. We're still lying about lifetimes, but it's a smaller lie
than before, where `SymbolStr` contained a (fake) `&'static str`!
Use `OutputFilenames` to generate output file for `-Zllvm-time-trace`
The resulting profile will include the crate name and will be stored in
the `--out-dir` directory.
This implementation makes it convenient to use LLVM time trace together
with cargo, in the contrast to the previous implementation which would
overwrite profiles or store them in `.cargo/registry/..`.
