This patch updates the cmake options suggested when cross compiling. This should fix [#52819](https://github.com/llvm/llvm-project/issues/52819).

Brad King (Member of CMake) says:

The linked [CMAKE_CROSSCOMPILING](https://cmake.org/cmake/help/v3.22/variable/CMAKE_CROSSCOMPILING.html) documentation says:

This variable will be set to true by CMake if the `CMAKE_SYSTEM_NAME` variable has been set manually (i.e. in a toolchain file or as a cache entry from the cmake command line).

It is not meant to be set by project code or toolchain files. It is always set automatically. Don't put `set(CMAKE_CROSSCOMPILING ON)` anywhere in your code.

`CMAKE_CROSSCOMPILING` indicates only whether `CMAKE_SYSTEM_NAME` was set by the user/project/toolchain-file instead of by CMake.

In LLVM project, `CMAKE_CROSSCOMPILING` is used to determine whether to execute some tests on the host machine.

LLVM needs to use another method for that. `CMAKE_CROSSCOMPILING` is not a reliable indicator of whether produced binaries will run on the host, and does not claim so in its documentation. If one sets `CMAKE_SYSTEM_NAME` to Linux in a toolchain file, and builds on a Linux host, that doesn't mean the target architecture or minimum glibc version is the same.

Otherwise it becomes asymmetric in the types it accepts.

I think the i32 in the pattern prevents this from matching on RV64,
but using IsRV32 is safer.

Add tests for RV64 to make sure we don't print zip or unzip
because we incorrectly picked ZIP_RV32/UNZIP_RV32.

If the "reciprocal-estimates" attribute is present and it doesn't
contain "all", "none", or "default", we previously crashed on f16
operations.

This patch addes an 'h' suffix' to prevent the crash.

I've added simple tests that just enable the estimate for all
vec-sqrt and one test case that explicitly tests the new 'h' suffix
to override the default steps.

There may be some frontend change needed to, but I haven't checked
that yet.

This patch adds assemblyFormat for omp.parallel operation.

Some existing functions have been altered to fit the custom directive
in assemblyFormat. This has led to their callsites to get modified too,
but those will be removed in later patches, when other operations get
their assemblyFormat. All operations were not changed in one patch for
ease of review.

The code was considering shifts by an about larger than the number of
bits in the original VT to be out of range. Shifts exactly equal to
the original bit width are also out of range.

I don't know how to test this. DAGCombiner should usually fold this
away. I just noticed while looking for something else in this code. The
llvm-cov report shows that we don't have coverage for out of range shifts here.

This wasn't supposed to be commited yet

getShiftAmountTy will return MVT::i32 if the shift amount
coming from the target's getScalarShiftAmountTy can't reprsent
all possible values. That should eliminate the need to use the
pointer type which is what we do when LegalTypes is false.

This removes clangd's existing workaround in favor of proper support

Add `ObjCProtocolLoc` which behaves like `TypeLoc` but for
`ObjCProtocolDecl` references.

RecursiveASTVisitor now synthesizes `ObjCProtocolLoc` during traversal
and the `ObjCProtocolLoc` can be stored in a `DynTypedNode`.

In a follow up patch, I'll update clangd to make use of this
to properly support protocol references for hover + goto definition.
