No behavior change as GNU ld/gold/ld.lld ignore --dynamic-linker in -r mode.
This change makes the intention clearer as we already suppress --dynamic-linker
for -shared, -static, and -static-pie.
This patch adds has_value, value, value_or to llvm::Optional so that
llvm::Optional looks more like std::optional.
I will keep the existing functions while migrating their callers and
then remove them later.

I'd like to introduce functions, such as value, value_or, has_value,
etc to make llvm::Optional look more like std::optional. Renaming
value to val avoids name conflicts.

Old LLVM installation may expose its internal omptarget CMake target when being used by find_package(LLVM) and caused issues in the CMake of libomptarget that is being built. Trap the issue early.

Follow up from flipping dialects to both, flip accessor used to prefixed
variant ahead to flipping from _Both to _Prefixed. This just flips to
the accessors introduced in the preceding change which are just prefixed
forms of the existing accessor changed from.
Mechanical change using helper script
https://github.com/jpienaar/llvm-project/blob/main/clang-tools-extra/clang-tidy/misc/AddGetterCheck.cpp and clang-format.
This patch implements a necessary part of P0848, the overload resolution for destructors.
It is now possible to overload destructors based on constraints, and the eligible destructor
will be selected at the end of the class.
The approach this patch takes is to perform the overload resolution in Sema::ActOnFields
and to mark the selected destructor using a new property in FunctionDeclBitfields.
CXXRecordDecl::getDestructor is then modified to use this property to return the correct
destructor.
This closes https://github.com/llvm/llvm-project/issues/45614.

We wanted to check if all uses of the function are direct calls, but the
code didn't account for passing the function as a parameter.

Allow cold fragment to get new address.
Our previous assumption is that a fragment (.cold) is only reached
through the main fragment of same function. In addition, .cold fragment
must be reached through either (a) direct transfer, or (b) split jump
table. For (a), we perform a simple fix-up. For (b), we currently mark
all relevant fragments as non-simple. Therefore, there is no need to
get new address for .cold fragment.
This is not always the case, as function entry can be rarely executed,
and is placed in .text.cold segment. Essentially we cannot tell which
the source-level function entry is based on hot and cold segments,
so we must treat each fragment a function on its own. Therfore, we
remove the assertion that a function entry cannot be cold fragment.
Test Plan:
```
ninja check-bolt
```

Type legalization will convert the bitcast into a vector store and
scalar load.
Instead this patch widens the vector to v8i1 with undef, and bitcasts
it to i8. v8i1->i8 has custom handling for type legalization already to
bitcast to a v1i8 vector and use an extract_element.
The code here was lifted from X86's avx512 support.

Marked all dialects that could be (reasonably) easily flipped to _Both
prefix. Updating the accessors to prefixed form will happen in follow
up, this was to flush out conflicts and to mark all dialects explicitly
as I plan to flip OpBase default to _Prefixed to avoid needing to
migrate new dialects.
Except for Standalone example which got flipped to _Prefixed.

This mostly handles folding of constants that have already become loads, but we expose some generic load cases as well.
This also exposes the chance to merge unary shuffles across X86ISD::ANDNP nodes with different scalar widths
`getCurrentFile` here causes an assertion on some condition.
`getCurrentFileOrBufferName` is preferrable instead.
