Matthias Krüger 1494755275 Rollup merge of #150426 - ZuseZ4:offload-register-lib, r=davidtwco
Update offload test and verify that tgt_(un)register_lib have the right type

Apparently, we weren't running offload tests when Enzyme wasn't built. Time to fix that.
Also adds a test mode which generates the host IR, but does not expect device IR/artifacts. This way, we don't have to handle artifacts and paths in our tests.
Also removes some outdated documentation.

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
