Jonathan Brouwer 16c7ee5c05 Rollup merge of #151640 - ZuseZ4:cleanup-datatransfer, r=nnethercote 
Cleanup offload datatransfer

There are 3 steps to run code on a GPU: Copy data from the host to the device, launch the kernel, and move it back.
At the moment, we have a single variable describing the memory handling to do in each step, but that makes it hard for LLVM's opt pass to understand what's going on. We therefore split it into three variables, each only including the bits relevant for the corresponding stage.

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
