You can add automated testing for SSE2 as follow:
- define `SSE2_OPT` similar to `ROUND_OPT` flag in `libc/cmake/modules/LLVMLibCFlagRules.cmake`
- expand `${SSE2_OPT_FLAG}` similar to `${ROUND_OPT_FLAG}` in `libc/cmake/modules/LLVMLibCObjectRules.cmake`, function `_get_common_compile_options`
- add `FLAGS SSE2_OPT` inside `add_header_library(bitmask ...)` in `libc/src/__support/HashTable/CMakeLists.txt` above.

Then all tests and targets depending on `libc.src.__support.HashTable.bitmask` will be extended to both with and without SSE2.
