  [C++20] [Modules] Handle transitive import in the module properly

Close https://github.com/llvm/llvm-project/issues/84002

Per [module.import]p7:

> Additionally, when a module-import-declaration in a module unit of
> some module M imports another module unit U of M, it also imports all
> translation units imported by non-exported module-import-declarations
> in the module unit purview of U.

However, we only tried to implement it during the implicit import of
primary module interface for module implementation unit.

Also we didn't implement the last sentence from [module.import]p7
completely:

> These rules can in turn lead to the importation of yet more
> translation units.

This patch tries to care the both issues.

These test cases show (op (ext a), (ext b)) patterns where the dest EEW is
more than 2 * source EEW. These could be lowered into widening ops where we
still have extend the operands, but at a smaller EEW.

  [clang] Add some CodeGen tests for CWG 4xx issues (#83715)

This patch covers the following defect reports:
[CWG438](https://cplusplus.github.io/CWG/issues/438.html) "Possible flaw
in wording for multiple accesses to object between sequence points",
[CWG439](https://cplusplus.github.io/CWG/issues/439.html) "Guarantees on
casting pointer back to cv-qualified version of original type",
[CWG441](https://cplusplus.github.io/CWG/issues/441.html) "Ordering of
static reference initialization",
[CWG462](https://cplusplus.github.io/CWG/issues/462.html) "Lifetime of
temporaries bound to comma expressions",
[CWG492](https://cplusplus.github.io/CWG/issues/492.html) "`typeid`
constness inconsistent with example".

[CWG475](https://cplusplus.github.io/CWG/issues/475.html) "When is
`std::uncaught_exception()` true? (take 2)" requires a libc++abi test.
As for [CWG454](https://cplusplus.github.io/CWG/issues/454.html) "When
is a definition of a static data member required?", I don't feel
confident in my understanding of it, so skipping over it.

  [InstCombine] Fix infinite loop in select equivalence fold (#84036)

When replacing with a non-constant, it's possible that the result of the
simplification is actually more complicated than the original, and may
result in an infinite combine loop.

Mitigate the issue by requiring that either the replacement or
simplification result is constant, which should ensure that it's
simpler. While this check is crude, it does not appear to cause
optimization regressions in real-world code in practice.

Fixes https://github.com/llvm/llvm-project/issues/83127.

  [InstCombine] If inst in unreachable refers to an inst change it to poison (#78444)

Instructions in unreachable basic blocks are removed, but terminators
are not. In this case, even instructions that are only referenced by
a terminator, such as a return instruction, cannot be processed
properly.

This patch changes the operand of a return instruction in an
unreachable basic block to poison if it refers to the instruction,
allowing the instruction to be properly processed.

Fixes #65107.

  [C23] Implement N3018: The constexpr specifier for object definitions (#73099)

The implementation mostly reuses C++ code paths where possible,
including narrowing check in order to provide diagnostic messages in
case initializer for constexpr variable is not exactly representable in
target type.

The following won't work due to lack of support for other features:
- Diagnosing of underspecified declarations involving constexpr
- Constexpr attached to compound literals

Also due to lack of support for char8_t some of examples with utf-8
strings don't work properly.

  [mlir][gpu] Replace MLIR_GPU_TO_HSACO_PASS_ENABLE by more generic one. (#84001)

This is another follow-up of #83004. The PR replaces the macro
`MLIR_GPU_TO_HSACO_PASS_ENABLE` with the more generic macro
`MLIR_ENABLE_ROCM_CONVERSIONS`. Until now, the former has been defined
if and only if the latter evaluated to true in CMake. However, the
former was not defined when the latter evaluated to false, in which case
a warning was raised if compiled with `-Wundef`. Using a single macro
relies on the `#cmakedefine01` mechanism that ensures the macro is
always set to either 0 or 1.
