bors 9f48a85447 Auto merge of #115050 - khei4:khei4/codegen-move-before-nocapture, r=nikic 
add codegen test for the move before passing to nocapture, by shared-ref arg

This PR adds codegen test for https://github.com/rust-lang/rust/issues/107436#issuecomment-1685792517 (It seems like this works from llvm-16?)

Fixes #107436

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
