Enforce use of `LLVM_SYS_*_PREFIX` when `LLVM_PLUGIN_PREFIX` is specified
If one compiles a plugin by manually specifying the LLVM installation path through LLVM_PLUGIN_PREFIX, LLVM_SYS_*_PREFIX should be specified as well.
Failing to do so would compile just fine, however there would be a link-time failure on windows:

D:\a\llvm-plugin-rs\tests\plugins\target\debug\deps\plugin1.dll : fatal error LNK1120: 10 unresolved externals
This is due to llvm-sys not building libwrapper when it fails to find llvm-config (which happens precisely when LLVM_SYS_*_PREFIX isn't set and LLVM is not in the system PATH).
There should be a compile time error when LLVM_PLUGIN_PREFIX is used without LLVM_SYS_*_PREFIX.
[question] is there a way to register the custom pass in inkwell's passmanager?
Hi, I'm building a compiler using inkwell, and want to add some custom passes to the inkwell's PassManager like below:
Is there any way to do so?

Support llvm 17
https://github.com/TheDan64/inkwell just got support for llvm 17, so hopefully a release will be on crates.io soon. Then it'd be awesome to see support in this crate.
SIGSEGV when loading hello world example pass
Hello,
A few months ago I ported this repo to LLVM 15 to use with the rust compiler, but whenever I tried loading the produced passes, I would get a SIGSEGV in rustc. At the time I thought this was entirely my fault, and gave up due to time constraints and the difficulty of debugging something inside WSL. However, now that this repo has properly been updated to LLVM 15, I gave it another shot, but I'm getting the same issue. When compiling the hello world pass example and loading it into a test program I get this error message:
To reproduce:
- Compile the hello-world example pass.
- Create a new project with
cargo init --bin - In the file
.cargo/config.toml, underbuild.rustflags, add an option-Zllvm-plugins=(PATH_TO_PASS)and-Cpasses=hello-world. - Compile the new project.
Please let me know if you can reproduce it or if I'm doing something completely wrong. I'm gonna try to investigate a bit further, but I'm not experienced in working with rustc, so any help would be appreciated.
