In the process of determining whether two MachineOperands are equal and calculating the hash of a MachineOperand, both MO_RegisterMask and MO_RegisterLiveOut types were uniformly handled. However, when the type is MO_RegisterLiveOut, calling getRegMask() triggers an assertion failure. This PR addresses this issue.
In C++17, static constexpr members are implicitly inline, so they no longer require an out-of-line definition. Identified with readability-redundant-declaration.

…m#166026) This patch improves readability by using "ArrayRef<T>" instead of "const ArrayRef<T>" and "const ArrayRef<T> &" in function parameter types.
fixUTF8 takes StringRef, so we do not need std::move here. Identified with performance-move-const-arg.
This reverts commit 7de242b. The previous landing contained a logic error where it actually forced the use of the external shell everywhere, causing some test failures on Windows. This patch pretty much keeps the existing structure of the code, just defaulting to the internal shell everywhere instead of only on Windows.
This patch adds env prefixes to some environment variables that get set inside a hwasan test. This broke when enabling the internal shell on AArch64 and was not caught as I did not test precommit there.
…1/N) (llvm#161142) Some checks use regular expressions to match option values in their implementation but this is not documented, it might makes user confused.

…166038) Fix an incorrect order in `ReleaseNotes.rst`
This was another test that was not using an env prefix when setting an environment variable. This was caught by the Sparc Solaris builder as it is disabled by default on Linux. https://lab.llvm.org/buildbot/#/builders/13/builds/10414
…is_within_lifetime`) (llvm#165243) <https://wg21.link/P2641R4> Implements the C++26 function in `<type_traits>` [meta.const.eval] (and the corresponding feature test macro `__cpp_lib_is_within_lifetime`) ```c++ template<class T> consteval bool is_within_lifetime(const T*) noexcept; ``` This is done with the `__builtin_is_within_lifetime` builtin added to Clang 20 by llvm#91895 / 2a07509. This is not (currently) available with GCC. This implementation has provisions for LWG4138 <https://cplusplus.github.io/LWG/issue4138> where it is ill-formed to instantiate `is_within_lifetime<T>` with a function type `T`.
