bors 23718020b1 Auto merge of #146148 - Flakebi:global-addrspace-test, r=Mark-Simulacrum
Add amdgpu test for addrspacecasting global vars and the gpu-kernel calling convention

Add two tests that can now be added, as the amdgpu is merged.

- Global variables are casted to the default address space since rust-lang/rust#135026
- gpu-kernel calling convention, translatos to amdgpu_kernel rust-lang/rust#135047

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
