Rollup merge of #144875 - scottmcm:more-mir-tests, r=cjgillot 
Add some pre-codegen MIR tests for debug mode

No functional changes; just some tests.

I made these for rust-lang/rust#144483, but that's going in a different direction, so I wanted to propose we just add them to help see the impact of other related changes in the future.

README.md

The goal of this directory is to track the quality of MIR that is given to codegen in a standard -O configuration.

As such, feel free to --bless whatever changes you get here, so long as doing so doesn't add substantially more MIR.
