[X86][Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - allow CRC32 intrinsics to be used in constexp

[RKSimon]

unsigned int _mm_crc32_u8 (unsigned int crc, unsigned char v)
unsigned int _mm_crc32_u16 (unsigned int crc, unsigned short v)
unsigned int _mm_crc32_u32 (unsigned int crc, unsigned int v)
unsigned __int64 _mm_crc32_u64 (unsigned __int64 crc, unsigned __int64 v)

https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html#text=crc32

These should be implemented using the descriptions in the Intel Intrinsics documentation, and tested offline to confirm runtime and constexpr implementations match.

TEST_CONSTEXPR needs to be added to sse42-builtins.c

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.
