Fix issue with callsite inline attribute not being applied sometimes.

If the calling function had more target features enabled than the callee than the attribute wasn't being applied as the arguments for the check had been swapped round. Also includes target features that are part of the global set as the warning was checking those but when adding the attribute they were not checked.

Add a codegen-llvm test to check that the attribute is actually applied as previously only the warning was being checked.

Tracking issue: rust-lang/rust#145574

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
