Since LLVM 22 the alloca must be passed directly. Do this by stripping the addrspacecast if it exists.
As Intel has walked back on the existence of AVX 10.1-256, LLVM no longer uses evex512 and avx-10.n-512 are now avx-10.n instead, so we can skip all the special handling on LLVM 22.

Rollup merge of #151410 - llvm-22-fixes, r=cuviper Fixes for LLVM 22 compatibility This includes three fixes for LLVM 22 compatibility: * Update the AMDGPU data layout. * Update AVX512 target feature handling. `evex512` is no longer used and `avx10.[12]-512` are now just `avx10.[12]`, matching the Rust feature name. * Strip address space casts when emitting lifetime intrinsics. These are now required to directly work on the alloca. r? @cuviper

Update to LLVM 22 Scheduled release date: Feb 24 1.94 becomes stable: Mar 5 Changes: * Update to rc2, with one patch to work around our outdated illumos sysroot (rust-lang/llvm-project@41256ab). * Update the host toolchain as well, otherwise we lose cross-language LTO, in particular for jemalloc. * Adjust one loongarch assembly test. The split into r and s variants is based on the suggestion in #151134. Depends on: * [x] #151410 * [ ] #150756 * [x] llvm/llvm-project#175190 * [x] llvm/llvm-project#175912 * [x] llvm/llvm-project#175965 * [x] llvm/llvm-project#176195 * [x] llvm/llvm-project#157073 * [x] llvm/llvm-project#176421 * [x] llvm/llvm-project#176925 * [x] llvm/llvm-project#177187
