Rollup merge of #132259 - mrkajetanp:branch-protection-pauth-lr, r=davidtwco 
rustc_codegen_llvm: Add a new 'pc' option to branch-protection

Add a new 'pc' option to -Z branch-protection for aarch64 that enables the use of PC as a diversifier in PAC branch protection code.

When the pauth-lr target feature is enabled in combination with -Z branch-protection=pac-ret,pc, the new 9.5-a instructions (pacibsppc, retaasppc, etc) will be generated.

ba481518da Add --print host-triple 
People often parse `-vV` output to get to the host triple, which is
annoying to do. It's easier to just get it directly.

2d476222e8 Add -Zfunction-return={keep,thunk-extern} option 
This is intended to be used for Linux kernel RETHUNK builds.

With this commit (optionally backported to Rust 1.73.0), plus a
patched Linux kernel to pass the flag, I get a RETHUNK build with
Rust enabled that is `objtool`-warning-free and is able to boot in
QEMU and load a sample Rust kernel module.

35f03b763e Move invalid-llvm-passes test to invalid-compile-flags folder 
Nowadays there is an `invalid-compile-flags` folder, thus move this
one there.
