bors 5dcb678ad8 Auto merge of #122917 - saethlin:atomicptr-to-int, r=nikic
Add the missing inttoptr when we ptrtoint in ptr atomics

Ralf noticed this here: https://github.com/rust-lang/rust/pull/122220#discussion_r1535172094

Our previous codegen forgot to add the cast back to integer type. The code compiles anyway, because of course all locals are in-memory to start with, so previous codegen would do the integer atomic, store the integer to a local, then load a pointer from that local. Which is definitely _not_ what we wanted: That's an integer-to-pointer transmute, so all pointers returned by these `AtomicPtr` methods didn't have provenance. Yikes.

Here's the IR for `AtomicPtr::fetch_byte_add` on 1.76: https://godbolt.org/z/8qTEjeraY
```llvm
define noundef ptr `@atomicptr_fetch_byte_add(ptr` noundef nonnull align 8 %a, i64 noundef %v) unnamed_addr #0 !dbg !7 {
start:
  %0 = alloca ptr, align 8, !dbg !12
  %val = inttoptr i64 %v to ptr, !dbg !12
  call void `@llvm.lifetime.start.p0(i64` 8, ptr %0), !dbg !28
  %1 = ptrtoint ptr %val to i64, !dbg !28
  %2 = atomicrmw add ptr %a, i64 %1 monotonic, align 8, !dbg !28
  store i64 %2, ptr %0, align 8, !dbg !28
  %self = load ptr, ptr %0, align 8, !dbg !28
  call void `@llvm.lifetime.end.p0(i64` 8, ptr %0), !dbg !28
  ret ptr %self, !dbg !33
}
```

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
