Auto merge of rust-lang#136861 - klensy:no-init, r=<try>

[experiment] dont init anything except x86

What if do not init all llvm targets always? Maybe fix regression in rust-lang#134740

r? `@ghost`
`@rustbot` label +S-experimental

btw, here https://github.com/rust-lang/rust/blob/c182ce9cbc8c29ebc1b4559d027df545e6cdd287/compiler/rustc_llvm/llvm-wrapper/PassWrapper.cpp#L81-L186 similar list for targets, but it missing amdgpu. Is amdgpu works without it?

kick perf run please
