Update to LLVM 15

For preliminary testing. Some LLVM 15 compatibility fixes were applied separately in rust-lang#99512.

Release timeline:
 * LLVM 15 branched on Jul 26.
 * The final LLVM 15.0.0 release is scheduled for Sep 6.
 * Current nightly (1.65.0) is scheduled for Nov 3.

Changes in this PR (apart from the LLVM update):
 * Pass `--set llvm.allow-old-toolchain` for many Docker images. LLVM 16 will require GCC >= 7.1, while LLVM 15 still allows older compilers with an option. Specify the option for builders still using GCC 5.4. rust-lang#95026 updated some of the used toolchains, but not all.
 * Use the `+atomics-32` target feature for thumbv6m.
 * Explicitly link libatomic when cross-compiling LLVM to 32-bit target.
 * Explicitly disable zstd support, to avoid libzstd.so dependency.

New LLVM patches ([commits](https://github.com/rust-lang/llvm-project/commits/rustc/15.0-2022-08-09)):
