On nightly (rustc 1.50.0-nightly (c919f490b 2020-11-17) I can run
/home/matthias/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/rustc ./75323.rs -Zsave-analysis which works fine, but this no longer works with the master toolchain (c4f836a); this worked yesterday!
/home/matthias/.rustup/toolchains/master/bin/rustc ./75323.rs -Zsave-analysis

error: the option `Z` is only accepted on the nightly compiler
