[BUG] Compiler crash on X86 DAG->DAG Instruction Selection

[dmitry-salin]

Bug description

Mojo compiler fails to build library tests: https://github.com/dmitry-salin/io_uring
I think it fails because library uses inline assembly.
The older nightly version mojo 2024.9.905 (ae516e17) compiles the same code without problem.

Steps to reproduce

In the repo root directory (Mojo installed with magic) run:

magic run mojo build run_tests.mojo

Output:

[2588687:2588687:20240925,023052.454548:ERROR elf_dynamic_array_reader.h:64] tag not found
[2588687:2588687:20240925,023052.454640:ERROR elf_dynamic_array_reader.h:64] tag not found

Please submit a bug report to https://github.com/modularml/mojo/issues and include the crash backtrace along with all the relevant source codes.
Stack dump:
0.	Running pass 'Function Pass Manager' on module '<split-module-llc>'.
1.	Running pass 'X86 DAG->DAG Instruction Selection' on function '@main'
Segmentation fault (core dumped)

Run:

magic run mojo test
