Recipes for interleave group members are recorded directly in the
RecipeBuilder. Use it directly instead of going indirectly through
VPlan's Value->VPValue mapping.

A previous patch update the clang-tidy documentation
incorrectly claiming that SystemHeaders can be provided
in the .clang-tidy configuration file.

This patch adds support for it, together with tests.

I removed the barriers a bit fast. Some mold is needed on
hlfir.elemental for polymorphic vector subscripted designator (and for
parenthesized polymorphic) so that a temporary can be later created.

The parenthesized array case may also just used asExpr and that
could later use AssignTemporary to deal with this. But the vector
subscripted designator case will need to use some new runtime
to get some mold allocation done for the temp.

Add TODOs in the meantime.

Fixes #62412

Prefix occurrences of `//utils/bazel` with an explicit `@llvm-raw`.

This change lets us reuse code from `configure.bzl` in future compatibility patches for the bzlmod
module system.

The llvm-project overlay will be made available as an `@llvm-project-overlay` (name WIP) module in
the Bazel Central Registry. This means that we will have an `@llvm-project-overlay` workspace in
addition to the `@llvm-raw` and `@llvm-project` workspaces currently involved in the build. To keep
future patches to the existing build files as small as possible, the explicit naming proposed in this
change appears to be the simplest way to not confuse the module workspace resolution.

This is not a functional change to the current WORKSPACE build. It is a foundation for future patches.

The patch implements a helper function that matches and fold the following cases in the InstCombine pass:

    bswap(logic_op(x, bswap(y))) -> logic_op(bswap(x), y)
    bswap(logic_op(bswap(x), y)) -> logic_op(x, bswap(y))
    bswap(logic_op(bswap(x), bswap(y))) -> logic_op(x, y) in multiuse case, which still reduces the number of instructions.

The helper function accepts bswap and bitreverse intrinsics. This patch folds the bswap cases and remain the bitreverse optimization for the future

Fold the following case on IR InstCombine pass. This patch includes the new test cases for this optimization

bswap(logic_op(x, bswap(y))) -> logic_op(bswap(x), y)
bswap(logic_op(bswap(x), y)) -> logic_op(x, bswap(y))
bswap(logic_op(bswap(x), bswap(y))) -> logic_op(x, y) with multi-use

Motivation:

```
#include <string_view>

size_t findFirst_ABCDEF(std::string_view sv) {
  return sv.find_first_of("ABCDEF");
}
```

memchr("ABCDEF", C,  6) != NULL -> (C == 'A' || C == 'B' || C == 'C' || C == 'D' || C == 'E' || C == 'F') != 0

Previously the event expression would be misidentified as a port list.
A line break would be added after the comma.  The events can be
separated with either a comma or the `or` keyword, and a line break
would not be inserted if the `or` keyword was used.  We changed the
behavior of the comma to match the `or` keyword.

Before:
```
always @(posedge x,
         posedge y)
  x <= x;
always @(posedge x or posedge y)
  x <= x;
```

After:
```
always @(posedge x, posedge y)
  x <= x;
always @(posedge x or posedge y)
  x <= x;

In `libomptarget` we use a couple of functions from `libomp`, but we didn't link
`libomptarget` against `libomp`. That will not work on some platforms such
as macOS. A linker error will be encountered because those symbols are not resolved
at link time when building `libomptarget`. This patch simply makes `libomptarget`
link agains `libomp`, makes it a "user" of `libomp`. I think this will not break
the policies between `libomp` and `libomptarget`.

The recently added ObjC Language unittest, InvalidMethondNameParsing, currently has CPlusPlusLanguage as its language label (see https://reviews.llvm.org/D149804). There is already a test with the same name and same language label in the C++ Language unittests, so this creates a name conflict. This patch corrects the language label on the ObjC test.
