URL: https://github.com/llvm/llvm-project/commit/8815328b6bf0f8c5088f6df73ad853a5aba159d9 DIFF: https://github.com/llvm/llvm-project/commit/8815328b6bf0f8c5088f6df73ad853a5aba159d9.diff LOG: [clang][x86] Add constexpr support for all remaining TBM intrinsics (#110515) BEXTRI is already handled, so we just need to tag the rest of the intrinsics, which are all expanded to generic patterns. As these are expanded I felt it better to test against the equivalent pattern instead of the final result (I intend to take the same approach for BMI/BMI2 cases).
