[X86][Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - add AVX512 KTEST/KORTEST intrinsics to be used in constexpr

[RKSimon]

Followup to #158653 - the AVX512 mask predicate KTEST intrinsics should be able to be used in constexpr - probably by interp__builtin_elementwise_int_binop?

unsigned char _ktestc_mask16_u8 (__mmask16 a, __mmask16 b)
unsigned char _ktestc_mask32_u8 (__mmask32 a, __mmask32 b)
unsigned char _ktestc_mask64_u8 (__mmask64 a, __mmask64 b)
unsigned char _ktestc_mask8_u8 (__mmask8 a, __mmask8 b)
unsigned char _ktestz_mask16_u8 (__mmask16 a, __mmask16 b)
unsigned char _ktestz_mask32_u8 (__mmask32 a, __mmask32 b)
unsigned char _ktestz_mask64_u8 (__mmask64 a, __mmask64 b)
unsigned char _ktestz_mask8_u8 (__mmask8 a, __mmask8 b)

int _mm512_kortestc (__mmask16 k1, __mmask16 k2)
unsigned char _kortestc_mask16_u8 (__mmask16 a, __mmask16 b)
unsigned char _kortestc_mask32_u8 (__mmask32 a, __mmask32 b)
unsigned char _kortestc_mask64_u8 (__mmask64 a, __mmask64 b)
unsigned char _kortestc_mask8_u8 (__mmask8 a, __mmask8 b)
int _mm512_kortestz (__mmask16 k1, __mmask16 k2)
unsigned char _kortestz_mask16_u8 (__mmask16 a, __mmask16 b)
unsigned char _kortestz_mask32_u8 (__mmask32 a, __mmask32 b)
unsigned char _kortestz_mask64_u8 (__mmask64 a, __mmask64 b)
unsigned char _kortestz_mask8_u8 (__mmask8 a, __mmask8 b)

A stretch goal would be to handle these as well:

unsigned char _ktest_mask16_u8 (__mmask16 a, __mmask16 b, unsigned char* and_not)
unsigned char _ktest_mask32_u8 (__mmask32 a, __mmask32 b, unsigned char* and_not)
unsigned char _ktest_mask64_u8 (__mmask64 a, __mmask64 b, unsigned char* and_not)
unsigned char _ktest_mask8_u8 (__mmask8 a, __mmask8 b, unsigned char* and_not)

unsigned char _kortest_mask16_u8 (__mmask16 a, __mmask16 b, unsigned char* all_ones)
unsigned char _kortest_mask32_u8 (__mmask32 a, __mmask32 b, unsigned char* all_ones)
unsigned char _kortest_mask64_u8 (__mmask64 a, __mmask64 b, unsigned char* all_ones)
unsigned char _kortest_mask8_u8 (__mmask8 a, __mmask8 b, unsigned char* all_ones)

Hi!

This issue may be a good introductory issue for people new to working on LLVM. If you would like to work on this issue, your first steps are:

1. Check that no other contributor is working on this issue. If someone is assigned to the issue or claimed to be working on it, ping the person. After one week without a response, the assignee may be changed.
2. Leave a comment indicating that you are working on the issue, or just create a pull request after following the steps below. Mention this issue in the description of the pull request.
3. Fix the issue locally.
4. Run the test suite locally. Remember that the subdirectories under test/ create fine-grained testing targets, so you can e.g. use make check-clang-ast to only run Clang's AST tests.
5. Create a Git commit.
6. Run git clang-format HEAD~1 to format your changes.
7. Open a pull request to the upstream repository on GitHub. Detailed instructions can be found in GitHub's documentation. Mention this issue in the description of the pull request.

If you have any further questions about this issue, don't hesitate to ask via a comment in the thread below.
