... otherwise CC at the time of building dev-lang/rust is baked in,
which is problematic if e.g. CC=clang-19 is used and then it gets
depcleaned later (as reported on the gentoo-user ML).

1. target in ALL_LLVM_TARGETS has prefix llvm_targets_, so the check in
last commit failed always.
2. using associate array for the test of experimental target's existence
3. sed -i 's:LLVM_EXPERIMENTAL_TARGETS:RUST_EXPERIMENTAL_TARGETS:g' to
fix warning on var name collide with ALL_LLVM_EXPERIMENTAL_TARGETS in
llvm.org.eclass

current experimental targets are defined from v1.73 only, so the final
experimental target list should be the intersection of
ALL_LLVM_EXPERIMENTAL_TARGETS in ALL_LLVM_TARGETS.

This workaround is only required when migrating from non-slotted
Rust to slotted Rust. Since these versions have never had
a non-slotted counterpart, this step is superfluous.
Remove it now in conjunction with an unrelated revbump so that
the workaround isn't carried forward any further.

For a reason lost to the sands of time, Gentoo was previously
disabling the `rpath` option in the Rust config.toml and instead
adding Rust the Rust lib path to `ld.so.conf` via entries installed
in `/etc/env.d`.
This was fine before we enabled slotting on the Rust package, however
with increasing numbers of Rust slots a hash collision was inevitable
and eventually happened between 1.84.0 and 1.84.1, resulting in
`undefined symbol` errors when invoking `rustc` or `cargo`.
Since we install Rust in a very similar way to upstream, it makes
sense to set the `RUNPATH` to `$ORIGIN/../lib` as their packaging
does and not pollute ld.so.conf with Rust paths.
This enables dev-lang/rust binaries to search relative to
their install location, and will therefore always respect EPREFIX.
Also drop obsolete 1.82.0-r100; no need to revbump that.
