Rollup merge of #129350 - krasimirgg:llvm20, r=nikic 
adapt integer comparison tests for LLVM 20 IR changes

The LLVM commit abf69a167b changed the IR in a few comparison tests:
https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/30500#01917017-26fe-4a4d-956b-725a2903e5a8

Adapted accordingly.

README.md

The files here use the LLVM FileCheck framework, documented at https://llvm.org/docs/CommandGuide/FileCheck.html.

One extension worth noting is the use of revisions as custom prefixes for FileCheck. If your codegen test has different behavior based on the chosen target or different compiler flags that you want to exercise, you can use a revisions annotation, like so:

// revisions: aaa bbb
// [bbb] compile-flags: --flags-for-bbb

After specifying those variations, you can write different expected, or explicitly unexpected output by using <prefix>-SAME: and <prefix>-NOT:, like so:

// CHECK: expected code
// aaa-SAME: emitted-only-for-aaa
// aaa-NOT:                        emitted-only-for-bbb
// bbb-NOT:  emitted-only-for-aaa
// bbb-SAME:                       emitted-only-for-bbb
