Should be good now, but
1. switching from checking value type to rhs makes new negative test to pass
2. this in turn made me reverse the change for `legalize-load-memory-metadata.mir`
3. multiple checks for error messages within one negative test do not work because it crashes once, I can split three negative cases in three files or keep single check for error message

Let me know what do you think, thank you!
