rustc_llvm: Link to libkstat on Solaris/SPARC
getHostCPUName calls into libkstat but as of
LLVM 16.0.6 libLLVMTargetParser is not explicitly
linked against libkstat causing builds to fail
due to undefined symbols.

This restricts instructions to those offered by Pentium,
to support e.g. AMD Geode.
There is already an entry for this target in the NetBSD
platform support page at
src/doc/rustc/src/platform-support/netbsd.md
...so this should forestall its removal.
Additional fixes are needed for some vendored modules, this
is the changes in the rust compiler core itself.
rustc_llvm: Link to `zlib` on dragonfly and solaris
On native builds `llvm-config` picks up `zlib` and this gets pased into
the rust build tools, but on cross builds `llvm-config` is explicitly
ignored as it contains information for the host system and cannot be
trusted to be accurate for the target system.
Both DragonFly and Solaris contain `zlib` in the base system, so this is
both a safe assumption and required for a successful cross build unless
`zlib` support is disabled in LLVM.
This is more or less in the same vein as rust-lang#75713 and rust-lang#75655.

Convert all the crates that have had their diagnostic migration
completed (except save_analysis because that will be deleted soon and
apfloat because of the licensing problem).
The majority of the code is only used by either rustbuild or
rustc_llvm's build script. Rust_build is compiled once for rustbuild and
once for every stage. This means that the majority of the code in this
crate is needlessly compiled multiple times. By moving only the code
actually used by the respective crates to rustbuild and rustc_llvm's
build script, this needless duplicate compilation is avoided.
This fixes warning when building Rust and running tests:
```
warning: library kind `static-nobundle` has been superseded by specifying `-bundle` on library kind `static`. Try `static:-bundle`
warning: `rustc_llvm` (lib) generated 2 warnings (1 duplicate)
```
