[llvm][AArch64] Fix an interaction of SLS and BTI after a returns twice call

This fixes the combination of two things:
* Placing a BTI after calls to a returns twice function like setjmp.
  This allows the setjmp to return with a br instead of a ret.
* Straight line speculation mitigations that replace BLR with a BL
  to a thunk that does the mitigation, and then goes to the original
  target.

Originally I marked AArch64call_bti as requiring that SLS mitigation
be disabled. This caused a crash when you tried to codegen with both.
Since CALL_BTI tried to match with AArch64call_bti but could not.

This change does 2 things:
* Follow the pattern set by AArch64call and add 2 patterns for
  AArch64call_bti. One with no IP (interprocedural) registers,
  and one with. For SLS mitigation on and off respectively.
* Modify the sls hardening pass to iterate through bundled
  instructions, as the AArch64 KCFI pass does.

Since there is a 1:1 replacement of the BLR with a BL,
the bundle remains intact. This is checked with an MIR test.

The ir -> asm testing is updated to add runs with the sls
mitigation enabled.

[mlir] Make the vast majority of integration and runner tests work on Windows

This patch contains the changes required to make the vast majority of integration and runner tests run on Windows.
Historically speaking, the JIT support for Windows has been lacking behind, but recent versions of ORC JIT have now caught up and works for basically all examples in repo.

Sadly due to these tests previously not working on Windows, basically all of them are making unix-like assumptions about things like filenames, paths, shell syntax etc.
This patch fixes all these issues in one big swoop and enables Windows support for the vast majority of integration tests.

More specifically, following changes had to be done:
* The various JIT runners used paths to the runtime libraries that assumed a Unix toolchain layout and filenames. I abstracted the specific path and filename of these runtime libraries away by making the paths to the runtime libraries be passed from cmake into lit. This now also allows a much more convenient syntax: `--shared-libs=%mlir_c_runner_utils` instead of `--shared-libs=%mlir_lib_dir/lib/libmlir_c_runner_utils%shlibext`
* Some tests using python set environment variables using the `ENV=VALUE cmd` format. This works on Unix, but on Windows it has to prefixed using `env ENV=VALUE cmd`
* Some tests used C functions that are simply not available or exported on Windows (`fabsf`, `aligned_alloc`). These tests have either been adjusted or explicitly marked as `UNSUPPORTED`

Some tests remain disabled on Windows as before:
* In SparseTensor some tests have non-trivial logic for finding the runtime libraries which seems to be required for the use of emulators. I do not have the time to port these so I simply kept them disabled
* Some tests requiring special hardware which I simply cannot test remain disabled on Windows. These include usage of AVX512 or AMX

The tests for `mlir-vulkan-runner` and `mlir-spirv-runner` all work now as well and so do the vast majority of `mlir-cpu-runner`.

Specifically, it verifies that if pointers are involved, that both result and source types are pointers, that this also applies to vector of pointers and that pointer casts are of the same address space.

The only thing left unverified is the general case of "source type size does not match result type size". I think this case is less trivial and more prone to false positives, so I did not yet implement it.

[flang] Warn on mismatched DATA substring sizes rather than crashing

When a DATA statement initializes a substring with a character constant
of the wrong length, do the right thing with blank padding or truncation,
and emit a warning.  Current code is crashing due to an unhandled error
reported from the low-level data image initialization framework.

17 months ago[libc] Add a loader utility for AMDHSA architectures for testing
Joseph Huber [Mon, 6 Feb 2023 17:01:20 +0000 (11:01 -0600)]
[libc] Add a loader utility for AMDHSA architectures for testing

This is the first attempt to get some testing support for GPUs in LLVM's
libc. We want to be able to compile for and call generic code while on
the device. This is difficult as most GPU applications also require the
support of large runtimes that may contain their own bugs (e.g. CUDA /
HIP / OpenMP / OpenCL / SYCL). The proposed solution is to provide a
"loader" utility that allows us to execute a "main" function on the GPU.

This patch implements a simple loader utility targeting the AMDHSA
runtime called `amdhsa_loader` that takes a GPU program as its first
argument. It will then attempt to load a predetermined `_start` kernel
inside that image and launch execution. The `_start` symbol is provided
by a `start` utility function that will be linked alongside the
application. Thus, this should allow us to run arbitrary code on the
user's GPU with the following steps for testing.

```
clang++ Start.cpp --target=amdgcn-amd-amdhsa -mcpu=<arch> -ffreestanding -nogpulib -nostdinc -nostdlib -c
clang++ Main.cpp --target=amdgcn-amd-amdhsa -mcpu=<arch> -nogpulib -nostdinc -nostdlib -c
clang++ Start.o Main.o --target=amdgcn-amd-amdhsa -o image
amdhsa_loader image <args, ...>
```

We determine the `-mcpu` value using the `amdgpu-arch` utility provided
either by `clang` or `rocm`. If `amdgpu-arch` isn't found or returns an
error we shouldn't run the tests as the machine does not have a valid
HSA compatible GPU. Alternatively we could make this utility in-source
to avoid the external dependency.

This patch provides a single test for this untility that simply checks
to see if we can compile an application containing a simple `main`
function and execute it.

The proposed solution in the future is to create an alternate
implementation of the LibcTest.cpp source that can be compiled and
launched using this utility. This approach should allow us to use the
same test sources as the other applications.

This is primarily a prototype, suggestions for how to better integrate
this with the existing LibC infastructure would be greatly appreciated.
The loader code should also be cleaned up somewhat. An implementation
for NVPTX will need to be written as well.
