This change allows building the static OpenMP runtime, `libomp.a`, as
WebAssembly. It builds on the work done in [D142593] but goes further in
several ways:
- it makes the OpenMP CMake files more WebAssembly-aware
- it conditions much more code (or code that had been refactored since
[D142593]) for `KMP_ARCH_WASM` and `KMP_OS_WASI`
- it fixes a Clang crash due to unimplemented common symbols in
WebAssembly
The commit messages have more details. Please understand this PR as a
start, not the completed work, for WebAssembly support in OpenMP.
Getting the tests running somehow would be a good next step, e.g.; but
what is contained here works, at least with recent versions of
[wasi-sdk] and engines that support [wasi-threads]. I suspect the same
is true for Emscripten and browsers, but I have not tested that
workflow.

This patch changes AArch64 + `__GNUC__` to use `__sync` builtins to
implement internal atomic macros just like for Unix, because mingw-w64
is missing some of the intrinsics which the MSVC codepath is using.
Then some remaining intel-only functions are removed from dllexport to
fix linking.
This should fix https://github.com/llvm/llvm-project/issues/56349.

Detect, through CPUID.1A, and show user different core types through
KMP_AFFINITY=verbose mechanism. Offer future runtime optimizations
__kmp_is_hybrid_cpu() to know whether running on a hybrid system or not.

This patch partially prepares the runtime source code to be built with
-Wconversion, which should trigger warnings if any implicit conversions
can possibly change a value. For builds done with icc or gcc, all such
warnings are handled in this patch. clang gives a much longer list of
warnings, particularly for sign conversions, which the other compilers
don't report. The -Wconversion flag is commented into cmake files, but
I'm not going to turn it on. If someone thinks it is important, and wants
to fix all the clang warnings, they are welcome to.
Types of changes made here involve either improving the consistency of types
used so that no conversion is needed, or else performing careful explicit
conversions, when we're sure a problem won't arise.
Patch is a combination of changes by Terry Wilmarth and Johnny Peyton.

to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

In these places the const attribute seems correct and doesn't
need any other change, so let's do it.

.clang-format's comments are removed and a (hopefully) final
set of formatting changes are applied.

Removes semicolons after if {} blocks, function definitions, etc.
I was able to apply the large OMPT patch cleanly on top of this one
with no conflicts.

Changes are: replaced C-style casts with cons_cast and reinterpret_cast;
type of several counters changed to signed; type of parameters of 32-bit and
64-bit AND and OR intrinsics changes to unsigned; changed files formatted
using clang-format version 3.8.1.

This patch contains the clang-format and cleanup of the entire code base. Some
of clang-formats changes made the code look worse in places. A best effort was
made to resolve the bulk of these problems, but many remain. Most of the
problems were mangling line-breaks and tabbing of comments.
