Add MIR pre-codegen tests to track 138544

Make `checked` ops emit unchecked LLVM operations where feasible

2024-04-19T01:11:21+00:00

For things with easily pre-checked overflow conditions -- shifts and unsigned subtraction -- write then checked methods in such a way that we stop emitting wrapping versions of them. For example, today neither ```rust a.checked_sub(b).unwrap() ``` nor ```rust a.checked_sub(b).unwrap_unchecked() ``` actually optimizes to `sub nuw`. After this PR they do.

Update `checked_ops` so 32- and 64-bit gets the same checks

2024-04-18T16:35:36+00:00

Remove some only- clauses from mir-opt tests

2024-03-18T14:07:43+00:00

[AUTO_GENERATED] Migrate compiletest to use `ui_test`-style `//@` directives

2024-02-22T16:04:04+00:00

Allow to run filecheck in mir-opt tests.

2023-10-19T15:51:52+00:00

remove some unnecessary ignore-debug clauses

2023-08-24T12:10:18+00:00

Remove brittle test.

2023-06-01T21:41:58+00:00

Restrict test to x64.
