the option `--global-isel` will trigger a crash.
Crash has be reproduced in `llvm-18.1.2`, `llvm-16` and `llvm-14`.
Reproduced with:
`/mnt/llvm-project-llvmorg-18.1.2/build/bin/llc --global-isel /mnt/data/acpi_listen.bc -o /mnt/data/acpi_listen.s`
trace:
```s
LLVM ERROR: unable to legalize instruction: G_BRJT %23:_(p0), %jump-table.0, %19:_(s64) (in function: handle_cmdline)
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
