Here's the bitcode file which can reproduce the slowdown with
> clang -target i686-unknown-linux-android libregex_automata.regex_automata.b5dfadd7c666403-cgu.0.rcgu.bc -c
Running it with -mllvm -opt-bisect-limit=-1 shows the pass and function where LLVM hangs:
> BISECT: running pass (2021) remove-loads-into-fake-uses on function (_RNvNtNtCsYvqlNLYD0R_14regex_automata4meta8strategy3new)
